I am sorry you feel so bad all the time. You need to see a good diagnostic center, perhaps Mayo clinic. They do get to the bottom of things, testing for just about everything over a period of days. Also a teaching hospital is a good bet, where there are more "heads" on your case. There is nothing worse than feeling bad, and never knowing why. Have you been tested for Lymmes? There are so many obscure conditions, regarding the immune system. T @ B Lymphocyte test is what showed for me at Mayo clinic. These are the fighter cells, that were misdirected. My hair fell out also. It started with a nasty virus which never really left. Do not give up, as many treatments are available if you can just get the DX. We will be here for you, and so will I. I hope you feel better soon and can find some resolution. ginnie
