Another thing that in my experience was close to magic was immersing sore limbs in ice baths. I had a near career-ending bout of RSI a decade ago. Physical therapy and fancy peripherals were unhelpful. But a couple months of nightly 10 minute soaks of my arms in buckets of ice water is the closest I've ever come to a miracle cure. Sadly, it didn't seem to work for anyone else who tired it. I think what it did was to reset my hypersensitive pain threshold back to normal, but I don't have any science to back that up. It was intensely uncomfortable (bringing me close to tears after a couple minutes) at first but then I adjusted to it.
