Have you talked to a doctor about this? This seems like an odd condition, usually with repetitive use the fingers will strengthen and skin will thicken to cause you less sensitivity. I'm not a doctor but there are a number of medical conditions that can present symptoms like this. Could be something as common as carpal tunnel but it could also be lack of blood flow, infections, arthritis setting in or other odd things. I would definitely speak to a doctor if you haven't and even if you have maybe a few different doctors.
