I've been playing with Danny (drums) for about 2 years. That's a long time for someone in a Navy band. The other guys kind of rotate in and out.
Had the surgery on November 1st. I was back on my bass in about 3 weeks, I'm really glad I decided to go ahead with the surgery. My grip is still really weak and the incision site is sort of tender, but now no more carpal tunnel symptoms. I'd say my chops are at a 110% + from what they were 6 months ago.
