i really got scared when i read about this. my dr says because mine is a direct nerve injury the rsd will stay where it is. it's just the ulnar nerve that's hurt so it's just the ulnar nerve's range that's affected. i'm 18 months in and it's unchanged. i really hope and pray that it stays right where it is, that was my big scare when he first diagnosed it and gave me info. but both my pain drs say that rsd2 stays at the injury site. i'm so sorry that yours didn't and i'm really hoping that my drs are right about this. somehow.
