I haven't had the surgery for my carpal tunnel but did have one cortisone shot when it was bothering me a lot on my left hand. When mine was really bad and it made it harder to sleep I found some gloves that immobilized the wrists which helped some. I was also told to try and keep them elevated when I could. It might help to talk with your hand doctor if possible to find out if something else besides the PMR is going on.
