Welcome!
Hmmm, I've never had much luck with steroids either and one dose of "crazy" was enough for me, so I've been able to refuse them thus far.
If you are not getting relief from the prednisone, I'd call the doctor's office and see what they can offer/suggest. Hopefully some others who are more familiar with that stuff will be around shortly to give you better advice.
Hang in there....I know how hard it is when you are in that much pain and can't get relief.
Don't forget to drink lots of water.
