Sensitivity to cold weather (or even air conditioning) is very normal with RSD. I've always lived in Illinois so even though I never really liked the cold weather I was used to it during the winter. Now...anytime I am somewhere where the temp is less than 70 it aggravates my pain.

Is your husband on any medications that might be responsible for the bleeding under the skin? Even if you have to go to a general practitioner he should probably see someone just to check it out, as it may not be related to the RSD.

Good luck with your shoulder surgery.
