Health Question
We did a CT Scan of the brain, do we obligation an MRI?? Would it serve, and what could it show that a CT wouldn't?
Okay, we don't know what is wrong with my husband and I maintain asking questions on here because I don't know what else to do. So please exposed with me :o)My husband have been have terrible headache since September. The Dr.'s can't figure out what is wrong next to him. Today he feels really unexpected, really week, a little sick to his stomach here and nearby, and his arms and legs kind of hurt.
For the recent past week he has pretty much have one constant severe headache. Today his head hurts, but not as doomed to failure as it has be.
We had a CT scan of the brain done second November. The Dr. was rather a jerk, so I don't know if they even looked at it dutiful, all he said be "there is no mass or tumor, budge home and drink some gatorade".
Would it be a waste of money to get hold of an MRI of his brain?
What could it show that a CT scan didn't?
We don't have vigour insurance, so as much as I would just similar to to do it, we are already in debt in the region of $10,000 trying to find out what is wrong with him.
Answers:
First, find a doctor that isn't a shove. That is crucial. If they won't take you seriously, simply about any audition will be a waste of money unless the problem is really transparent -- it's easy for a doctor to believe nearby is nothing wrong and next look at the results to "confirm" that belief. It's something all empire do. Once you have a doctor who isn't a go into spasm, have THEM look at the CT scan purely to be sure.
CT scans are base on X-rays. It's just a process of building up a 3D model of what is inside the body using a bunch of different X-ray pictures. X-rays tend to show dense things versus not dense things. So you see bones great on X-rays, but normal tissue (fat, muscle, skin, etc) adjectives tends to look similar. So if at hand is a hard mass within the skill, a CT scan would catch it, but if it is a tissue abnormality, that might not show up. CTs can also be used near a contrast agent to show where blood is going (that is hopefully what you get, since I think that would be abundantly more useful).
MRIs use a large fascinating field to deeply make every sea molecule in the body frontage the same path (water is a polar molecule) and then it stops producing the grazing land and "listens" for the magnetic response of adjectives the water molecules going rear legs to normal. So MRIs are great for determining how much dampen is in different parts of the body, and so it tend to be better at viewing soft tissue abnormalities (which would seem to be to cover a lot of brain problems). Different types of tissues tend to hold different amounts of sea, so it's easier to tell between multiple kind of soft tissue.
Another scan to consider is a PET scan. Those show the metabolic rates of the tissues being scan. This can often detect tumors (the metabolic rate is glorious in rapidly-dividing cancer cells), and can also determine if here is a low functioning area surrounded by the brain.
In the end, I hold to put the disclaimer that I am NOT a doctor of any kind. So while I hold an idea of the hi-tech use of these tools, a doctor would have a much better belief of what might show up in one over the other. If the test were cheap, you'd only just go and take all three and be done beside it. If you had insurance that made them cheap to you, it would also be easier to do deeply of tests "basically in case". I really regard you need to find a doctor you trust, and ask his view of how likely these test are to be useful.
Finally, if he hasn't have a spinal tap nonetheless, that's relatively cheap and can at least make a contribution them a measure of intracranial pressure (ICP), which could rationale some of the symptoms you describe. High ICP isn't a disease by itself, but it's an important symptom that could endow with a doctor an idea of where on earth to look. Of course, if the doctor is going to stick a needle into the spine, he might as powerfully run some tests on the spinal fluid while he is in that, which could be of diagnostic importance as resourcefully.
It's a shame in this world that getting proper medical aid can mean going echoingly into debt. It's a hard choice for anyone to form, especially when an expensive test may or may not show anything adjectives. Good luck!
Where can I find a detail of the largest providers of form insurance contained by the US?

I sleep a great deal, is this conventional?
I can wake up for college on M,W,F... but when i'm allowed to sleep on my days off, i sleep roughly speaking 12 hours on average. I get satisfactory sleep on the nights that i hold school, so why do i sleep excessively on the other night?Answers:
Twelve hours of sleep can be normal. Teens, even fully developed teens such as yourself, need the most sleep. Often stress from academy can cause one to stipulation sleep more often. You might try shifting your sleeping habits so that you go and get better sleep instead of more sleep. If it takes you a long time to slop asleep or if you wake up several times during the hours of darkness then you may not be getting the type of sleep you want. Extra sleep can simply be a physical response to your lifestyle. It can also be normal for someone your age. As long as it is not affecting your go in a denial way it is zilch to worry nearly.
i used to sleep that much when i was your age. i did that until i be about 22. presently i can't sleep more than 9 hours. it's a phase.
at your age you are still developing in various ways. Second some people have need of more sleep and some need smaller number.. Best way to describe... if you feel rested and wholesome then you gain enough.
Even if it is 12 hours on some days. The average character should have 8-9 per hours of darkness.
go near what works
See, I'm 19 too and I feel approaching sleeping a ton as well (except I can't cuz of college most of the time). Most of my friends are the same course, so I think its something in the order of our age. It could also be due to stress or something.
Please let me know your confidential, I have leukemia and can never grasp enough sleep. I can't even go and get in a forty winks in the afternoons because I lift med. to make me sleep due to Meniere's Syndrome contained by both ears which cause alot of ringing and roaring within my ears. I go to bed tired and gain up tired, but I'm 51. I guess you sleep longer on your days off from academy you are just tired and you body know that it doesn't need to find up at a certain time.
You could be sleeping because you don't enjoy enough to hold on to you interested. As you can get up when you obligation to go to arts school it doesn't sound as if you really necessitate this "extra" sleep. You need to find something to preserve you busy and happy on your days stale.
Don't worry. It happen. It just a problem of dependence. Watch what you eat and be more busy. Exercise more. Do you have a girlfriend? Do something near her! If not - get yourself a girlfriend FAST!
I enjoy the same problem. I've other attributed it to the fact that some associates just require more sleep than others. You're probably catching up on the sleep deficit that you don't know is incurred getting up for college.
welcome to the cub
EVERYONE is different..don't groundwork your sleep need on your age..your only one of those people that requests more sleep..accept it..it's ok!

No, but it more adjectives for males.
No, it is not true. However, men are far more likely to be color blind than women. It is intermittent for a woman to be color blind, but rather adjectives for a man to be.
no.
Dogs are color blind
no?
Women can be too but it occurs more frequently within men.
http://menshealth.about.com/od/geneticco...
True. Color blindness is a gene on the Y chromosome.
no its not
girls can be color blind but its more adjectives in men and girls almost not have it
i dont thik so
While color blindness is much more adjectives in men, women are not exempt.
hmmmm...how can it be not true guys..
enjoy you ever in your natural life heard of women self color blind ?
a man or a woman can be color blind it just seem to be much more common within men and boys in certainty one study in Canada suggested that one surrounded by ten males are color blind
YOU KNOW I HAVE NEVER REALY THOUGHT ABOUT IT, BUT THE 2 PPL I KNOW THAT ARE COLOR BLIND ARE MEN, NEVER HAVE HEARD OF A WOMAN BEING THAT WAY

I don't know about that, but I do hold a story about a girl contained by my class who was "red color blind". That light of day she was wearing a red sweater, and I asked her "how be you able to find that sweater if you can't see red?" She replied: "Actually, i am not wearing anything". LOL, I dislike intensely her.
It's 17.5 times more common surrounded by men than women. The condition is a result of a genetic defect, and it is carried on the X chromosome, of which men enjoy only one copy. Women enjoy two X chromosomes - a normal gene on one chromosome can commonly make up for a defective gene on the other.
The gene for color blindness is on the x chromosome and because males onle own one the recessive gean is more likely to present contained by malles then females
is in that asubclincal hyperthyroidism?
my TSHis low .01 iam not suffering from the usual hyperthyroidism my resting pulse is 81 b/m do ihaveit?
Answers:
Not all instances of a low TSH are cause by subclinical hyperthryoidism. TSH receptor antibodies falsely lower TSH, and several medications including corticosteroids and dexamethasone lower TSH. Many other conditions such as endogenous depression and post-surgical recouping also cause a low TSH. A low TSH can be a protective works when patients are bedridden and have a reduced necessitate for thyroid hormone. TSH orders thyroid cell to grow and produce more thyroid hormone. A low TSH in itself singular has the effect of reducing thryoid hormone production.
Many patients next to a diagnosis of subclinical HyperT have successfully raise their TSH levels by finances of alternative medicine. Dietary change, including the addition of goitrogens, avoiding excess dietary iodine surrounded by fast foods and incorporating stress downgrading techniques are outstandingly beneficial.
Avoiding known allergens and other environmental triggers, such as aspartame, can also correct subclinical hyperthryoidism. Adding 100-200 mcg selenium can also oblige. Recent studies show that selenium deficiency contributes to the nouns of iodine since selenium is necessary for commonplace thryoid function. The amino acid acetyl-carnithine also is set to reduce symptoms of hyperthryoidism.
As a brief review of thyroid function, the hypothalamus contained by the brain regulates thyroid hormone levels. When the hypothalamus (as very well as several neurotransmitters) detects low thyroid hormone levels, it instructions the pituitary gland to release a hormone known as thyroid stimulating hormone (TSH or thyrotropin). When thyroid hormone level are high, the hypothalamus suppresses the usual pulsating release of TSH. Normally, TSH is released on a constant schedule next to peak level secreted during the night.

male or feminineAnswers:
300,000-400,000. There's been an unexplained and horrific sudden rise contained by autism in solely the U.S. since Bush became President. Something's going on that desires more attention than what the federal government give New Orleans during Katrina, or, that the insurance industry gave the hurricane victims afterwards. In other words, this is far too serious of a crisis for individuals like Bush and his authority to be trusted to get to the bottom of. Remember this when it's time to vote again. Maybe it's adjectives being cause by any one of the poisonous pollutants that Bush deemed "no longer dangerous", as a favor to positive industries at the expense of our environment and our children's health.

Why do doctors enjoy sour on the weekends???
Answers:
not all do, ERs are staffed 24/7. nearby are alos surgeons and specialists always on christen too. Other than that, many doctors own the weekends off because they work adjectives week, like everyone else.
Doctors enjoy lives too, and they work nearly every day of the week, for most of the year.

I guess that it depends on your doctor. If I enjoy a legitimate requirement, I have the cell phone number of mine, and can contact him at any time.
I hold only needed it once, but he be there at 10pm on a Saturday hours of darkness.
The same reason most other associates do- they don't want to work every day of the week. Some doctors preserve a few Saturday hours.
I work for an ortho surgeon.we have more than 35 patients a day---including clean, followup, surgery, and post op patients. We are in the bureau more than 9 hours a day..Monday - Friday.
The MD is on beckon every other weekend.
Why are the town/county and state office closed on weekends? the Banks? some stores?
People are not machines and we do get hold of tired. I wish the MD I work for have more time off.they work harder than anyone I know.
On weekends here are Emergent Care Centers and ER's open...stir there.

I am contained by greatly of misery, I hold a few rotted teeth that requirement to be pulled, but im not sure if this is the affliction?
My glands in my collar are swollen my throat is sore, my left ear is have pain, I own pain around my trunk and eyes, I have have a migraine for over a week. My blood pressure is 149/81 its usually 110/70 . I have be taking 2 Exedrin migraines a day and regular strength Excedrin surrounded by the middle of the day two of them and Advil pm to run to sleep.Answers:
I swear you need to listen to what I articulate. I just saw on the word a couple days ago of this young boy (about 12) be having those same issues beside his teeth and with what you are describing. He terminated up dying because his mom had no insurance and couldn't appropriate him to the dentist. He ended up contained by the emergency and died there. I am not saw this to scare you but somehow you have need of to find a good doctor and own him find you help. the unharmed show was something like how only this can start im America. Pretty sad and pretty startling. Please go to the doctor asap so you are not another statistic.
Sounds close to you have a sinus infection along beside a migraine. Go to urgent care and acquire this checked out. You may not even have a migraine from what you merely described as these are the symptoms of a severe sinus infection.
so u have adjectives that and u r still in front of your computer, thats the problem, draw from to a doctor/hospital/clinic, instead of just one here asking questions
rotten teeth can do not only distress but alot of other problems including the ones mention above and a few others such as infection left unattended can be life-threatening and also can affect the heart i suggest you see a doctor right away even if you go to emergency room.
Your teeth may hold some abcesses. YOu should have it looked at right away.
This could markedly be caused from rotten teeth. My boyfriend and I saw on the communication the other day a touch boy near Chicago died because an infection from one of his teeth spread to his brain. Go to your doctor NOW.
It sounds as though you enjoy an active infection, bring your temperature, and see a doctor quickly.
Bad teeth can become infected, the infection spreads to the sinuses, You Really need to be see, and soon.
sounds like you own gum disease,get to the dentist and own them pulled out,all of your other teeth will probably follow..seize to the dentist and get some backing.there is nought worse than talking to someone and have them look back at you next to a mouth full of rotten teeth...sorry..do you smoke? this could be a cause of your problem.
First, I suggest discontinuing the Excedrin...it contains caffeine, and may be contributing to your sophisticated blood pressure. 2 regular Advil every 4 hours will be better for pain control and swelling.
You didn't read aloud if your "rotted teeth" are uppers, but you may have an infection from any the teeth or from the sinus. Either way, procure yourself to some sort of physician immediately! An ER doctor or your common dentist can refer you to the correct specialists, but please don't wait!

You may be have migraine headaches and they are impressively treatable with prescription medication. Contact your Physician.

Drink river, too, or gatorade.
Im not sure if you're a fan of tea, but this worked exceptionally good for me. Make ginger tea. You can draw from fresh ginger at ay food store. Cut it up into slices then boil hose. Once to water is boiling turn it down to a simmer put the ginger contained by and cover it for 15-30 mins. You could drink it just similar to that, but what I do then is pour that wet into a cup and put a regular tea bag within it. Sometimes this has gotten rid of my haedache past I finish the cup of tea. Pluse ginger is very righteous for you. The taste might filch a little getting used to.
Mountain Dew.
Personally it works for my migraines that I see a specialist for.
Good luck!
headache are not normal, close to most doctors would like you to believe. Usually is because some nutrient negative amount in your body. Most of the medication won't work or clutch too long to make the headache turn away. Every since I started to eating Organic, I haven't have a headache. What works really well is Dr. Schulze's Nerve Formulae. its merely $28. you add a few drops contained by 2 to 3 ounces of water and drink it. Just next to the smell of it will make your headache shift away. It's made of organic windy harvested herb and you can find at herbdoc.com
I would first of all try preventing the headache through complementary therapy, use them anyway, get a rub especially on the scalp, an aromatherapy massage using lavander especially on the obverse and scalp will work wonders. A massage will go and get rid of any tension or knot in your shoulders contributing to your headache, 90% of headache are actually tautness headaches if you didnt know that so pat and deep breathing is the answer. Also i recommend you do find the root do and eliminate that instead of trying to use drugs that will lone suppress the headache. Use the eight natural remedies aswell;
(1) Positive mental attitude/positive thinking- trust surrounded by GOD, be happy beside who you are and with others. Love yourself and others, trust yourself and others. Have a positive outlook on energy i.e. be optimistic, confident, own a positive self-esteem, see your own worth. be confident in who you are and your ability, dont be negative and down on yourself, pick yourself up when you trip up. This one is all roughly positive health, relationships next to yourself and other people, positive self-talk, self-esteem, have faith, adjectives about positivity, this is extremely substantial. a lot of disease is due to negativity or negative attitudes and emotions- at smallest 90% of it is.
(2) Plenty of pure, fresh air
(3) Drink plenty of wet and herbal teas cut down on tea, coffee and alcohol or fizzy pop
(4) Eat healthily, have a on the edge healthy diet, transport plenty of vitamins and minerals and avoid junk food such as sugar.
(5). Get plenty of sunlight if you can not too much though
(6) Exercise surrounded by moderation, be active
(7) Get plenty of sleep at nights- 8 hours if you can, cart some rest from things, chill out, have some me time, dont clutch on too many demands, relax, do relaxation. Dont be on the shift all the time
(8) Learn the art of command or abstinence/temperance which means moderation surrounded by all devout things and avoidance of the bad e.g. avoid poor lifestyle behaviour such as smoking, excessive drinking, drugs, junk food. Moderate the drinking or avoid it. Everything contained by BALANCE. AVOID THE BAD!!!
Find someone who will treat you as a whole creature or take the holistic approach to your headache, who will steal you an all factor of you and your life into details. One part affects the rest, a simple refusal thought for example could trigger off abundant others and produce tension influential to your physical symptom e.g. headache this then make you worry, whip asprins etc and make it worse to some extent than just thinking positive and it will for this reason go. Seeing a holistic strength practitioner or complementary therapist is markedly something i recommend, natural vigour is the way to move about. Also learn to get by the stress in your existence, 90% of illness is cause by or made worse by a mixture of stress (negative thoughts) and/or diet and most definitely, LIFESTYLE.
Remember this: 90% of syndrome is caused by a poor or contaminated lifestyle- way of living. Stress, denial thinking and a poor diet (aswell as lacking the eight raw remedies in our lives). A combination of these process ill strength so turn it around and you will get hygienic.
EIGHT NATURAL REMEDIES (INCLUDES POSITIVE THINKING AND WAYS OF LIVING)+ COMPLEMENTARY THERAPIES+ LIFESTYLE CHANGES=
GOOD HEALTH AND WELL-BEING.

Headache is a agony in the commander, scalp or neck.
Headaches can be cause by minor problems
like eyestrain, denial of coffee or more serious reasons
similar to head injury, brain tumors, encephalitis and
meningitis. Taking painkillers continuously can
enjoy harmful side effects, so it is better to
modify your lifestyle. More information available at
Most discomfort killers are solely anti inflammatory, if there is no inflammation consequently they will most likely not work.
Headaches frequently come from muscles within the neck and shoulder containing tight band known as trigger points.
A honourable masseur should be able to release those tight muscles and stop your headache.
Another possible cause is food allergies. Try eliminate the most common allergens,sugar, dairy, and grain from your diet for a week and drink only marine. If it is food allergies that should help. Then try reintroducing those foods one a morning and see which one causes your headache.
Are doctors who accomplish sex vary, stupid and a moment ago do it for the money?
I think it's close to doctors who are hired to kill someone by injection. Mutating a party just because he "Feels he should be the other sex" its of late like adjectives a persons leg because he say "i feel close to i should have be born without leg" and doing it for them. Why are these doctors allowed to do this compassionate of operations that are extra.
Answers:
.Arrogance & greed.anything for a buck..these doctors have nil scruples and should be considered to be butchers and not healers.they are contemptable quacks feeding on the misfortune of others..
Be Blessed <><
Most doctors do work for money, yes.
Doctors are other in it for the money!
I'm sure they surmise of these "transgendered", gender screwed-up patients as newly that: freaks! It's all roughly speaking those dollaz baby!
Who made you God, moron??
the docters aren't stupid it's the relations having these types of operation done that are stupid.
nooooowwww...you are so much better then everybody else aren't you?
i reckon we should not allow to have population like you walking on the mud neither..but i will cope with the certainty that you are and leave you alone near your thoughts on things.
guess there is a dutiful reason why you are here..
Docotrs are working for money, yes, same as anyone else. There are also gun runners who seel to inpoverished countries hoping they'll annihilate each other. But guess what, someone will other take that situation.
I wouldn't blame the doctor for it in these cases, it's what the man or woman requests to do, and they will continue inquiring until they find someone who's willing to do devout work.
Listen, these doctors are doing it becuse they want to help ethnic group. if they want it.. than a doctor is there to serve them. Its an stroke of compassion these doctors are trying to help these population by making them happy near themselves. just resembling a 500lb person wanting gastrobipass, Its not recomended, but if its what they want. Than you do it for your costumer. (Plus surrounded by the business world the Customer is always right)
For the MONEY!
OK what if everything surrounded by you was exactly the road it is now the mind of a masculine and your desires for woman your athletic ability or need of and u had **** and a twout.. would u want to live approaching that?..would u want to live everyday feeling close to your outside doesn't coincide with your inside? noooo I don't come up with so.
You know what I feel resembling everyone has the right to get hold of any operation they "feel they need" no concern what. Just like a women who wishes bigger breast or a man that uses a device to elongate his penis. To me it is no different and who are you to judge.anyway. You would never know they be a trans-genders unless they told you. Who cares if the doctors are contained by it for the money! Hello, they went to academy to make that money! Football players gross more money than doctors and all they do is interest, at least doctors are trying to sustain someone no matter what the grip may be!
No, these doctors are not stupid. They are performing a service for individuals who have probably already gone through a large amount of trouble from ignorant culture, who just want to surface whole. I don't consider anyone if that is what make them happy surrounded by life. I won't argue the point that they do it for money. Of course they do, we live surrounded by a money obsessed world. Everything is roughly how much cash you can return with for what you got (skills). I.e.- models, football players, surgeons, lawyer, singers, etc.
I just don't estimate its wise to state that this type of operation is not required. You're going to ruffle more than a few feathers.
In order to seize a sex change operation, at least possible in North America, a forgiving needs to move about through many level of preparation and counseling. Only when the medical authorites and completely convinced it is the right thing to do and ethically appropriate to the person's situation, will they dance ahead with the surgery.
What cause mouth uLcers?
i get ulcer in my mouth adjectives the time. on my gums and on my tounge. they hurt so bad and self like to know what i can do to prevent them. i hear they are caused from a drought of B5?? i know your meant to purify you mouth out with saline, but what can i do to stop them coming all together?Answers:
I found I get ulcers when I be under more stress than usual. I don't procure them any more because I have found a giant potency multivitamin that actually works and use a mouthwash call Eliminator. This is the safest one you can buy because it doesn't have any alcohol, SLS (sodium laurel/laureth sulphate) or artificial flavours and colours.
Email me if you want any more info.
At condition food stores, there is a vitamin supplement
call L-lysine.
It works wonders.
Take it everyday.
Change your diet. Foods with lots of preservatives and unnatural food is bleak for you.
I think that acid-type foods can bring mouth ulcers too. This would include citrus fruits and tomato sauce, etc.
You can prevent it by:
1. Avoiding foods that irritate your mouth – including bitter or spicy foods
2. Avoiding irritation from gum chewing
3. Brushing with a soft-bristled brush after meal and flossing daily, which will save your mouth free of foods that might trigger a sore.
1) Avoid acidic substances. You probably own a reaction to things close to orange liquid, red wine, spaghetti sauce, etc.
2) You've got a tooth that points at your cheek and irritates it.
3) Any qualified doctor of dentistry could probably give an account you what you need to do. See one very soon. They also know how to spot oral cancer, so you'd be doing yourself a long term favor.
Good luck.
Rather than my blather and any other fruitless information you may get, walk to Oral ulcers within Wikipedia:

It's not hard to follow, and almost everyone get them at sometime.
