T.P.
Very possibly carpal tunnel. Many people sleep with their wrists bent, which presses on the nerve and damages it over time. Even if you try hard not to sleep that way, your body may take over after you fall asleep and you may not even know you are doing it. You can try some cheap wrist "cock-up" splints from CVS or Walmart and see if it helps. Wear them when you sleep to keep your wrists from bending. A neurologist can do nerve conduction testing to test for sure if you think that is the proble.
