Hi Leiea,
I have CRPS in both my legs from hip to toes. I have had it for almost four years and I have noticed that when my legs are cold I have higher pain levels. For me that means that the fall and winter are a nightmare. I have found ways to combate the cold weather by purchasing a ton of the "warming patches" that are over the counter. I line these warmers in my socks up to the knee to get optimal coverage over the calf. I also put hand warmers in my pockets to try to keep the hip area warm. I have had a lot of success with the warmers as I hate when my legs get so cold that I feel like I'm going to freeze to death. Well that maybe dramatic but true.

Also, I have found when I have no movement I have more pain. It is important to keep moving the affected area, as I think if you dont use it you will lose it completely. I hope that helps and it was nice chatting with ya.

Oh yeah and stress does play a large role in my pain. Now I take anti anxiety meds and they seem to help with the pain.
