My neurologist said the final blow was last year when I sprained my thumb. But 10 years of flute, 6 of cheerleading, sewing, writing, computer time, and multiple injuries pretty much made meant I was going to get carpal tunnel at some point.
I have to wear brace at night for the moment, too keep me from sleeping with my wrist all curled up and squished, which is how I usually sleep. She also recommended it for long drives and when I'm just sitting and reading to keep my wrist in a neutral position.
If there's no improvement I get a cortisone shot in my wrist... Joy.
