I had to laugh at the post about sitting in the sun like a cat to warm up. My husband has had RSD since Feburary of 2009 (knee surgery) and that is what he is doing right now. We live in MN and when the temp gets below 20 degrees it is almost impossible to get him to leave the house. He takes alot of baths to try to warm up but sometimes warm water can feel boiling hot to him. I do not think the temp sensitivity has ever gone away but medication (Gabapentin) does help. He also uses a compounded cream that he can rub all over his leg for the pain and sensitivity to anything touching his leg.
