I would not go to the ocean and I live in South Florida. Not only for the reason of not being temp controlled but waves would be too ruff on my pain. I did pool therapy when I was at Cleveland Clinic. They had us walk like stated but also had dumb bells and noodle to do movements. I am nervousto try pool therapy again but am playing with the idea since for RSD I have heard benefits like stated. If I do it will be in a pool geared towards this with temps and calmness factor. I hope you find what works and you get pain relief
