Honestly it is hard to say..... for there are many medical problems that could cause the pain you are talking about.... take me as an example: I have RA & FIBRO and they both can effect my hands in the way you say your hands are reacting.

I would say GO SEE YOUR DOCTOR....... and see if there is any thing they can do for you and the hand discomfort.
