Welcome to the world of free knowledge people. Search engine websites are acting as biggest and widest knowledge source for self consultancy over billions of subject. Then why not Googling for a diagnosis? Why not to look at Wiki for disease information? And yahoo medical for drugs and medicine information?
Thats all you need to be consulting and being doctor yourself, however that is risky but nice enough to know about things you wanna know.
There are many article on Dr. Google, just ask google itself :))
