Ulnar nerve transposition, here, plus carpal tunnel work. Had fractured scaphoid as well and we had to wait until that healed (for whatever reason.) Spent six weeks in a full arm cast, then about a month afterwards in physical therapy before the surgery.
This all the result of an automobile accident.
Took about 18 months for the nerve to heal.
I was having extreme cramps of the hand and forearm. They were horrible! The fingers would try to fold over one another, my thumb(nail) would press so hard into my index finger, as to draw blood. Also on the second and third fingers, the first joints would move in flexion and the second joints would in extension. It was excruciating!
If I happened to have anything in my hand at the time, it became trapped: forks, knives, soda cans, etc.
I called them 'events' as they would last up to 10 minutes. Doctor thought I was exaggerating until it happened in his office one day. He warned me not to try to force them as it might result in a fracture, the muscles were locked down that completely.
When I woke up in recovery, I knew it was fixed. I mean it hurt like hell, but I could tell the problem was fixed.
