WebMD - diagnose yourself

This one is one I use all the time; it's WebMD. If you are ever feeling sickly or just have a random question about your health, this is the place for answers. They even have a Symptom Checker (scroll down on the left). It's a good tool when you don't have any idea whats wrong; you can click on the part of the body that hurts, and it will zone in on possible causes.

P.S. This is why there was no post yesterday - my wife ended up with an incredibly severe case of Poison Ivy and Impetigo. Don't know what Impetigo is? Well, check it out on WebMD.
