sounds like arthritis. Very common for the pain to increase when it gets cold. Swelling in the joints is also common. Try and keep the joints warm by wrapping them or wearing gloves if the knuckles hurt. aspirin or Ibuprophen are good for this type of pain of you don't have any stomach problems. And the hard part is to keep moving the joints that are affected. Keeping the joints immobilized will stiffen them up. Granted of course that you have arthritis.
