Over the last few weeks, I have been having some trouble with pain in my right hand. The pain is at the bottom of my hand, around the base of my thumb and just above the wrist. No tingling or numbness so far, just pain. Tried to ignore it so far, being a bloke. Sound like it could be carpal tunnel in my hand? My position has changed on my bike recently, but only to go back to the position that was recommended for me in a bike fit earlier in the year. Seems to mostly hurt on the bike when applying the brakes, which gives me the choice between pain and not braking . It sort of comes and goes, but often seems worse after a day at my job which involves using my hands and ergo my wrists to lift heavy things. So hard to say whether cycling or work related injury.
