Here's a link to my web page on carpal tunnel syndrome (as well as "tennis elbow" - more on that later).
http://www.doctor-harris.com/page5.htmlThe important thing to remember is that anything that causes swelling in the hand can result in carpal tunnel syndrome, as pressure is put on the median nerve in it's confined space at the wrist. So repetative, vibration inducing motion, such as drumming, can certainly cause this. Consequently, anything that can relieve that swelling may make your symptoms improve - including changing your drumming technique. Typically, CTS results in swelling and numbness at night (when you are horizontal instead of verticle, which increases the amount of fluid in your hands - while you are standing up that fluid is in your feet/legs). If you have a disease (like diabetes, thyroid disease, arthritis) that causes hand swelling, treating that disease may make your CTS improve.
I frequently see CTS problems with my drummer friends - I have them start out wearing a night time wrist cock-up splint that they can get from the drug store: this keeps them from flexing their wrists while they sleep and avoids putting further pressure on the median nerve at night. Anti-inflammatory medication such as Motrin has not provided long term relief very often in my experience. Steroid injections into the wrist for CTS are more likely to work on very acute (new onset) CTS, such as that associated with pregnancy or an injury like a fall. Long standing CTS only rarely permanently responds to steroid injections. I have seen many patients who have this problem with both hands.
CTS is primarily a problem with numbness of the thumb, index and middle fingers. Although it can cause pain, especially "electrical" type pain shooting up the arm, most pain problems are usually something else. CTS is primarily a tingeling/numbness problem - it's "pain" can feel like your leg does when it "goes to sleep" from sitting on it wrong for too long of a time.
Another problem drummers frequently share with me (especially percussionists) is "tennis-elbow", which is pain (and perhaps weakness with lifting) at the thumb side of the elbow. This, as opposed to CTS, usually responds well to steroid injections and/or therapy.
Pain in the small muscles of the hand, pain that you can elicite by pressing on a particular place in your hand, particularly around the base of the thumb, is more likely to be a sort of muscle cramp, which is also common among drummers. This usually responds best to massage and a change in stick holding techniques.
Pain at the very base of your thumb, where it plugs into your wrist, can be degenerative arthritis. This is painful when you are moving the thumb or putting pressure on the thumb, pushing it back into your wrist (grind test). Anti-inflammatory drugs (such as Motrin), splinting usually take care of this common problem, but sometimes it requires a fairly minor operation.
This are the causes of the vast majority of upper extremity pain that I see with drummers.
