I'm so sorry for the failure and the need to repeat the surgery!!! I just had a new nerve conduction study yesterday for my hand pain (and new numbness) and also on one leg. My word that is an uncomfortable test!!!!
Anyway, I have never had the "repeat" surgery, but apparently my bi-lateral CTS surgery was nowhere near as successful as expected and that does seem to explain the extra pain. I had trigger finger for a long time, but it eventually went away....I have no idea why.
I just wanted to give you some encouragement here. I had both my hands done at one time (and was fully awake). The first shot in each hand is somewhat uncomfortable (but not so bad that you can't stand it) and then you feel nothing but pressure. It really was not bad at all (until the recovery). Wow...when my hands woke up, I really knew it....but it was WAY better than being asleep because being asleep makes me feel so bad after. This was no big deal at all as far as surgery goes. There is no sickness from the general anestesia and no sedating effects when you get home. There was NO feeling during the surgery at all...HONEST!
I wish you all the best!
