I can relate to the cold. My foot/ankle often feels like it is in snow and almost that dethaw feeling after.It can be set off on a cold day or even in an air conditioned area that is super cold. This on top of the pain. For me baths help though sometimes I still remain cold foot after or it comes back. I can't tolerate heating pads or anything on it but we are all different. The doctor I said that many meds and treatment can help with the circulation but of course it is finding the right one which as of now is a hard battle
