I have relapsing-remitting MS. I also take Tecfidera among my medications, which include two different pain med regimens as well. When I was first diagnosed I had been so that I couldn't walk, aka my legs could not hold my body up, for three months - which I basically spent in bed. I also had very limited use of my left hand due to numbness which had taken over my fingers. I credit my gaming and computer use as well as the physical therapy for the fact my fingers are no longer numb and I have the use of the hand back almost to 100%.
