If it's being caused by a trapped nerve then there should be a good possibility that a release would result in remission. It's the same with neuroma or other physical problems. But there's a tendency for the swelling of RSD or something associated with RSD to give a sort of "false positive" for nerve entrapment. Operating under these conditions is extremely risky.

If it feels like an entrapment then that's one thing but it sure doesn't sound like one. There are few things RSD hates like on operation and that goes double for the affected limb.
