I use a percussive massager (not Theragun, but similar) with great results. My primary issue is numbness in the right foot, with periodic pain ( tingling, electrical shocks, pain in the ball of the foot, and some other non-PN issues). It has been very helpful - not a cure, but it eases the numbness for a few hours. And it feels great. I am using it on all of my muscles, and it is great on my back and calf muscles. One of the few PN related things I am glad I bought!
