I know a thing or two about Carpal tunnel so maybe I can be of some help.
Carpal tunnel syndrome is the impingement of the median nerve as it passes through the carpal tunnel in the wrist. The symptoms are numbness and tingling in the thumb, index, and middle finger. Muscle weakness in these digits can also happen, weakening your overall grip strength. The problem is caused and irritated by repetitive motion in your wrist. Diagnosis is by EMG (electromyograph) studies showing reduction in nerve conduction in the median nerve. Two simple tests to check for carpal tunnel include bending the wrist at 90 degrees and putting pressure on it (it should reproduce your symptoms) and tapping on the underside of your wrist in the middle (electric shocks should shoot to your fingertips if you have CTS). Treatment includes anti-imflammatory drugs like ibuprofen (motrin, advil), naproxen (aleve), and some stronger prescription meds like vioxx, celebrex, and bextra. These medicines work if used before you do your activity and are pain free, not after you have irritated the injury and have active swelling (you will still get some relief). Wrist braces, rest, and ice all do wonders as well and are highly encouraged. The surgery is not a great option but to someone who is not getting any relief, it may be the only option they have. What they do is cut the flexor retinaculum in your wrist to relieve the pressure. You loose some hand mobility as a result and as with all surgery you risk infection, further damage, and failure to achieve pain relief.
Feel free to post or email me questions.
