Hey there DWK,
Is that an acronym for Driving While KickingAS?
I feel for you on the prolonged pain with no respite and I hope it does come to an end for you soon.
The local pain clinic told me they weren't going to give me any shots since the peripheral pains were so widespread, they'd have to give me thirty shots. Still, one in the spine likely would have been nice anyway.
My own experience with corticosteroids is limited to Prednisone which definitely helped me a lot. The problems associated with Pred use are rather severe so it isn't a long term solution but it does work. I always mention my crash off of Pred whenever it comes up because that is the night I base my 10 on. My doctors had me on a conservative taper which proved to be too much and my system rebounded and freaked out with maddening pain...it was torture, pain and simple. The answer was to take MORE Pred!...and then continue to taper off more slowly.
Hopefully this will have nothing to do with your situation but on the off chance that it does, I would never want someone to have to suffer like that when the solution is so simple and right at hand.
