I have the same problem with my knees... I've been meaning to look into something that I can wear on my knees to keep them warm when I go for a walk.. because I find if I wear gloves it helps with the pain in my hands and wrists. I also take a lot of rests... and bathe in hot water more often if my knees are at their worst.

All taken at night to help me sleep and stop dreaming and it still doesn't help :P
