Hi

I’ve just the Netflix show as well. Very interesting.
Have suffered from RSD (old terminology) for about 23 years in my right foot.
Becoming a cyclist was the best fix for my pain, that I discovered.
I still have the occasional pain when I’m not riding regularly.
I’ve always used heat to settle pain, but after watching the show, even trying ice pack for ten minutes it seems very effective.
I will experiment more with a bucket of ice water.

Thank you for the discussion
Kind Regards
