Ditto.

When I had problems with my wrists, I started to play the piano, a lot. I would bang on the keys fortzando and make a lot of noise (the noise got better over time :).

I also had a small stress ball that I would squeeze as hard as I could several times throughout the day.

After two or three months, the pain, numbness, and swelling were gone, and have never come back these last dozen years.
