Hey Trina,
I don't know if you remember me mentioning this or not, but I had a bout with Hemolytic Anemia 6 years ago. By the time I dragged myself (almost literally) to the doctor, my hemoglobin was at 5.8 (normal range is 12.0 - 16.0). The hematologist said she was surprised I was able to walk in, and immediately admitted me to the hospital. I had a blood transfusion, followed by a several month course of prednisone.
The anemia hasn't recurred, but 2 years ago I had a platelet problem (6,000 when the normal range is 150,000 - 400,000). Another stint in the hospital and more prednisone. (O.K., so I respond well to prednisone, but it's not fun!)
Anyway, my point in relaying all this is that maybe there's a tie-in somewhere. Obviously, I'm a family member of a Moyamoya patient!
I hope your fatigue improves. Until you experience it, it's hard to believe how debilitating fatigue can be, and I remember well how I truly didn't want to even get out of bed. Not fun at all.
