Health Symptom Web Site

There are a lot of diseases, disorders, and syndromes out there. Most have a list of common symptoms associated with the problem. Let's say I have a problem with a tingling sensation in my fingers. Searching a popular health database will tell me that I may have Multiple Sclerosis, carpal tunnel, cancer, hepatitis or a bunch of other things. I may end up missing the true cause of my problem. However, if a web database let you input symptoms and did an intelligent match on possible causes, you would get better results. The greatest benefit of such a database would be that people with these problems would be able to input their own symptoms. Many undocumented symptoms could emerge. Back to my example; if several people with multiple sclerosis get muscle spasms in their face, they would input them to the master database. Muscle spasms are not a documented symptom however. As I am searching for my problem I may just have two symptoms - tingling in my hands and muscle spasms in my face. The database would then give me a high probability for multiple sclerosis.
