I'm having it done a week from Tuesday. Doctor told me that the bandage stays on for 24 hours. Then, wear wrist brace for one week, and avoid vibrations and heavy work for 4-6 weeks. The doctor is one of the best in Cleveland and uses the small incision. I searched for doctors that only do surgery on hands and arms. It's a good idea to research and find a top notch doctor and know what can be corrected and not. Any permanent nerve damage will not be corrected by the procedure, but typical symptons such as hand/arm "falling asleep" at night and pain should improve with the surgery.
Good luck! I'm writing this reply at 4 in the morning due to the typical nighttime effects of carpal tunnel...waiting for it to calm down, and back to bed I'll go.
