I have it also, Avoided surgery so far doing the same things as David. The exercises and the Braces at night, or driving long distances, playing on the computer too much...... I started trying to remember to wear them when I am tooling. I think they have helped my tooling some when I wear them because it keeps my wrist in a consistent position. And my elbow off the table. I have not found a way to carve with my swivel knife with them on yet. My braces came from the surgeon also. He did not like the OTC ones either.
I was not ready for the % of loss of use that comes with getting the surgery done.
