murgir - I agree with Bram about the hot wax. I couldn't handle any heat on my hands, can't imagine how that high heat from the wax would do This hot wax sounds like contrast therapy. Contrast therapy is bad for RSD/CRPS, the cold is the worst, but the extreme temp change to the heat can be just as bad. If it were me, I would stop it. I went to PT for my hand and they made it worse, they did the heat and tens on it. The desensitization was torture, but in small doses it helped. They talked about contrast therapy and I said "see ya!"

irpuregenius - Sorry you are having to deal with this. I do not have popping and locking in any of my affected areas, so I cannot help there. Glad you stopped the contrast baths.

Good luck to both of you!
