I had some Carpal Tunnel problems a couple years ago from using a pneumatic grinder, exacerbated by the commute to from work. The CT braces they sell in pharmacies are good if the problem is bad enough, and it keeps pressure off the nerve, by reinforcing the palm and keeping your wrists straight. I use padded gloves with wrist wraps on my longer rides. It works. Chronic numbness is a big deal, and if you don't get it taken care of within a certain amount of time, you run the risk of making it permanent.Just an FYI.
