Welcome to Neuro Talk. Glad you for this forum. There will be people to help you, who may know more about CRPS than your PT Does. Not all therapists are created equil. No cold therapy. My son is a OPT. He Does know about RDS and CRPS, as he was required to keep taking classes throughout his career. Find a therapist who knows what this awful condition is, one that knows how to help you. If he is requiring cold therapy, he is doing wrong by you. I hope that you can find someone else. ginnie
