I also was wondering how your ulnar nerve had gotten compressed?
from an accident, repetitive work injury??
where was the second compression that you had surgery for?

The reason I ask is I have TOS {thoracic outlet syndrome} due to repetitive work postures and uses, and often TOS symptoms show up as ulnar nerve, hand, wrist , arm, shoulder, neck and upper back troubles. And some will get RSD/CRPS along with TOS.

So I was wondering if you have any of those other problems with your RSD and ulnar compressions?

We have a TOS forum here too.
here's our thread with tons of info about TOS if you'd like to skim thru it-
