Is nearby any website where on earth I can enter symptoms and receive a diagnosis for free?

Answers: As previously suggested, http://www.webmd.com is a great resource. You can select the body part that hurts, enter a few symptoms and it will account some possible diagnoses. You should exercise caution within using the site. It does not replace visiting a trained and literary medical practitioner. But it may give you some qualified research that could prove to be considerate.
