My guess would be mononucleosis. I was a sick a lot as a kid and prob. had it then. However, in 94 I was dx with mononucleosis via blood... tests. That is when my life started down hill. I was also Dxed chronic fatigue. 1 yr ago, I was dxed sever MS. Too be this bad, I think I must have had it a long time. I just did not pay attention to the little tingles...
