Jamie, i totally agree with Deb, actually i didn't know you could even buy splints for carpal tunnel, i made mine up myself, i only found it helpful for sleeping only as it restricts your normal hand usage to much during the day.
If it comes to having to have the op, for me it was a real breeze, i was done down at the Geelong hospital at the day surgery part, only takes a few hours and was allowed to go home about an hour after the op.
