Fortunately I'm on Copaxone and have very few side effects. All of the interferon side effects bothered me so I opted for Copaxone. I've not read anything about steroids preventing problems but I know they sure help me in a flare. My first flare I warned everyone against steroids but after this last round, and the fact that it got me out of a flare so soon, it makes sense that it may be used in this situation. Let us know any new info you get.
