I also go hot and cold even in the limbs that don't have RSD. My body seems to be very sensitive to temperature changes. I think that it is worse for me also because I am a teenager.

My limbs affected by the RSD are usually the ones that are worse affected and go very hot and sweaty or cold. My mum can literally see sweat dripping out of my arms and it is very emarrassing. I saw my PM Dr last Tuesday and he too was amazed at how bad it was.

Sorry that I can't help you that much, just know that you aren't alone and are in my thoughts!!
