Re: I have a problem
Physical things to do would be all the typical exercises. Many of them are covered in e.g. Matt Furey's "Carpal Tunnel Fix" program.
Other than that it's hydration and stay away from inflamatory and add anti-inflamatory foods.
Supplements would be fish oil and MSM. If DMSO is allowed in your country and you make sure you know what you're doing you can try that.
Bring back the Zildjian Colaiuta stick!
