I have trouble with very cold days, but now I also have trouble in warm weather, too... I noticed this trend when we moved to The South. We used to live in CA, which was pretty dry until late winter/spring rains.
The biggest factor that affects me is barometric pressure changes, no matter what the temp is outside, cold or hot. If the barometer goes either up or down, my hip (1988 car accident, passenger) is hurting. I didn't notice it in seasons other than winter/spring until we moved to humid Georgia that has constant storms and weather changes.

Crohn's and UC are pretty darn crappy, but if you can't laugh at yourself, you'll cry.
I'd much rather laugh.
2001 Dx'd with UC. No remission. 5/2008 surgery, removal of 6" of left side colon. Dx changed to Crohn's. Remission for 8-9wks after surgery, symptoms returning after resuming 6MP.
