I feel so fortunate to be reading this post right now! I have only been to one PT session several months ago, but am scheduled to start aggressive PT again next week for RSD in both feet. I am also scheduled for my first nerve block. I am nervous and cautious about not only the procedure, but about the PT as well. I will be VERY candid with my therapist ahead of time, and make sure that they are FULLY AWARE that I am not willing to do the extreme heat/cold bs that has put you all in so much pain. I can understand warm/cool to a degree, as when my feet get so tight and swollen cool compresses or packs DO give me relief, and when I feel cold all of the time very hot baths feel wonderful. However, I can't fathom extreme cold temperatures being of any benefit to any of us. Thank you again for this wonderful thread. I am so glad to have found this site and all of you. I have been so lost on this damn internet looking for some sort of hope.
