I spent 6 years in the rehab field. lots of CTS patients. a lot of good can be had with a hand specialist, in conjunction with a PT/OT and massage therapist. treat not just in your wrist, but forearm grip muscles up to your elbow as well. pain management, flexibility, and anti inflamation modalities work wonders. drugs for pain are good, but dont give up on the MANUAL side of healing. if it affects your riding, you'll probably do better, ergonomically, with higher bars (not apes) with less of a pull-back angle. you may have to try a few to get comfortable.
heal up!
