I have never had pain issues prior to the ulnar nerve surgery.
I have had plenty of other surgeries for injuries and sinuses, but never a lasting pain issue.
My pain management doctor doesn't think it is CRPS cause it is not progressing, I don't have swelling and some other symptoms so he continues to say it is pain from MGUS.
I know like it was yesterday that my symptoms started within a week of my elbow surgery including the foot pain and discoloration.

I was treated for Lyme disease and confections to rule that out.
