Symptom Checker

I just used it yesterday, and while it's user friendly, it can't really pin down an exact dianosis. I really like the site for all the information, so if you use the checker as a starting point, it's good.

I've used it sometimes. It can be helpful, but with many symptoms, they can be caused by many different ailments. The Symptom Checker can be good to give you idea if you should seek medical attention or find out more about the problem you're having though. And WebMD has a good reputation (reliable info, provided by professionals).
