CRPS / RDS

My husband is 24 years old & was diagnosed with CRPS/RSD in September. He has had it since July 9th when he hit his leg, no one could find out what it was until last month. Since then he has had 1 shot of steroids in his back about a month ago & found no pain relief but for a few days his color did return to his foot/leg. They haven't prescribed him anything at all for pain, not even a single pain patch. After the steroid shot didn't work they but him on high blood pressure medicine and he cant tell a difference. He has been out of work since July 9th and he is only 24 years old, it seems like his life is ending and he does not want it to. So anyone with RDS/CRPS what have you received for treatment with the pain? Should the doctor be doing more? It just seems weird all hes been given it 1 steroid shot and blood pressure med. Somebody please help or at least give some advice, it would be really appreciated.
