Have you had a repeat neurography lately? Prior to my re do I was becoming very week I had trouble walking up the stairs I would become dizzy and sometimes unsteady. Dr Filler had to spend an additional 2 hours on my surgery this last time. The scar tissue had built up quite heavily around the ulnar nerve. He told me that the septra film from last time had not taken. This time he had placed a double dose. I am now having sever burning and color changes in my right arm. They believe it is from the sever compression on the nerve. I see Dr Filler on the 21st and at that time if the nerve has not calmed down then he will look into a ganglion block. Maybe it is possible you have scar tissue building up on the vascular area again.
I hope for the best.
Many Gentle Hugs
