I play the piano, draw, and type alot. Naturally, I got carpal tunnel. I wouldn't recommend getting surgery unless it is your last option. I see a chinese doctor that does all these massages and acupressure stuff on my hands and arms. He says that even blockages all the way up to my shoulder and contribute to carpal tunnel. It is extremely painful what he does to me and I am sore for a couple of days. But my carpal tunnel is gone. I go back to him every two weeks or so for more torture. I would recommend seeing a hand physical therapist first before considering surgery.
Also, with everything that you do, make sure you have good alignment.
