Thanks for posting that info . Yes I’d seen that case study …quite miraculous, similar to the lady in the film. I will say that ice is still the only thing that gives me mild relief …more so in the early days . I used to go dip in the cold ocean and swim with one leg ( no , I didn’t go round in circles!) earlier on my journey , but nothing as drastic as ice water immersion. I wonder if it’s too late ? I’ll keep you posted , as I might as well try it.
