Most people with MS find some relief from the IV steroid, solumedrol. It is very hight dose (1,000 - 1,200 mg per infusion ). I have not heard much relief from oral steroids though. Hang in there, you will feel better. This flares and then remits. You are obviously in a flare. Get as much rest as possible and take very good care of yourself. Eat really healthy and drink lots of water and rest. You will give your body the best change at resting and cooling that flare.
Good luck and keep us posted.
