Hi again lainey,Wow, I can't think of anything else you should or could be doing right now. You're very lucky to be getting the brain scan. Most people with CFS have a hard time convincing their Dr to do them. The reason we would want them to be done, is to rule out MS (Multiple Sclerosis), which looks just like CFS in the early stages. It's probably the problems you're having with your legs and memory, that has tipped the Dr off that MS is a possibility. The cognitive training and the physical therapy for staggering (dizziness) are both state of the art in treating CFS! So it sounds like you are right on track !But I will keep my fingers crossed that you don't have MS. Good luck! Let us know how the scan turns out. Take care.
