I agree with most of the other posters and you must realize that the fatigue alone can come from what your body goes through during a flare due to the pain, it is nothing short of exhausting. Short term memory? How many of us can function at 100% when constantly distracted by pain.

Other things to consider would of course be meds and perhaps lack of sleep.

I also suffer from migraine type pain and find that benzo's - klonopin, ativan, valium, tend to help most with these along with a dark cave.

I certainly may be wrong but I don't believe the memory and fatigue are so much symptoms of the disease as symptoms of the treatments and toll it takes on the body.
