Hi Jamie, i had the carpal tunnel done on one wrist a few years back, i was and still am very glad i had it done, never had a problem since the op.... , i had mine done down at the Geelong hospital at the day sugery, only in there a couple of hours and went home, it was a real breeze for me.. worse having a tooth pulled, i wouldn't hesitate to have it done on the other wrist if the time comes.
good luck
Brian
