I have well had double crush on my right side it was the tos and the carpel tunnel so there for i was being crushed at the wrist and my upper arm. I don't no if it made my symptoms any different or not. Perhaps it might in creases the pain that's about it now the tos surgery has been done i just had the emg done and the doctor did say that my carpel tunnel has gotten slightly better. But it has made no difference in the pain i have in my hand.
