It is definately median nerve involvement which is the nerve that runs in the carpel tunnel. Try to keep your wrists in neutral when riding or on the computer. When extending the wrists, there is less room in the carpel tunnel and can compress the median nerve, therefore causing symptoms in the first three digits. The usually exercises usually include light wrist strengthening and wrist flexor stretches (going backwards) as long as there is no pain, or increase in digit numbness/tingling.
