It's around 7 years since I had my surgery so difficult to remember how long it took but I can tell you it took a while. It was only days before I used my hands again but I had tingling for months afterwards. The surgeon explained that because the nerve had been interfered with, it sometimes took a very long time to settle after surgery - anything up to about a year. He was right too.
I think you just have to be careful. Try not to overuse it but at the same time don't keep it in a splint or immobilized 24/7 Have you tried just wearing a splint overnight to give it a rest? I do that because I still do all the things which gave me cts in the first place.
I hope your hand continues to improve & gets back to normal soon. Best wishes.
