Swimtime,

Glad the scar is not stuck down! and if the nerve block didn't help then why bother. There can be a place for oral steroids in early CRPS. Some studies have indicated 10mg 3x daily for three weeks. Even a Medrol dosepak could make a difference in the right circumstances. If a lot your son's pain is inflammatory a steroid burst might knock that down and allow pain reduction and progress. I hit steroids twice in my ongoing recovery. Once about 3 months in and again about 6-8 weeks later. Made a definite difference and wasn't long term enough to be a problem.
