I have no experience with the steroids that you listed. I have used others in the past, with no success.
Please investigate the possible side effects. It has been observed that high-dose corticosteroids or long-term use of steroids increases the occurrence of diabetes. (Steroids raise the blood sugar level.)
My hypothesis: excess insulin (hyperinsulinemia) plays a major role in MS, as developed in my initial post: http://www.thisisms.com/forum/general-discussion-f1/topic1878.html "Insulin – Could This Be the Key?"
