When I go outside in the cool weather, my left hand becomes painfully cold when it's not even really cold. My right hand doesn't do that. My left didn't either before, but a heavy box fell on my hand a few years ago and crushed it. Could this be related?
Without knowing your medical history and seeing you, it is impossible to tell you what is wrong with your hand. But, in general terms, sometimes a crushing injury to a hand can cause a long-lasting problem called a neuroma, a bundle of nerves that have developed into a growth. For some people, a neuroma can cause problems such as pain and stiffness, and intolerance to the cold, as you describe.
The best thing to do would be to go to a doctor and have him or her examine your hand. Only then could a diagnosis be made.
