New tool helps diagnosis

I don't recommend making your own diagnosis but it never hurts to have ideas about what might be happening to you to run by the doctor.  MEDgle is a new website that let's you type in a symptom per line and then shows you conditions that match your symptoms.  Definitely a useful tool!  Use it to get ideas, to find things to ask the doctor about and to learn about conditions.
