I had moderate ulnar nerve repair on both elbows 2 yrs ago. This past month the scars (which are about 6-7 inches long) have begun to have a burning/icy sensation to them. It has become painful sometimes. I have a 20 year history of ulnar nerve problems. I also have a history of overproducing scar tissue at surgical sites, examples are adhesions after shoulder injury which led to a frozen shoulder requiring manipulation under anesthesia, adhesions from 3 c sections requiring a 4 hour surgery/hysterectomy, frozen elbow etc. I cant understand the burning,stinging,icy sensation to scars on elbows. Very frustrating and discouraging.
