I use a hi-dow unit I picked up in Placid last year during Ironman…
Works great for nerve/shoulder pain. I have a metal plate on my left collar bone from an accident with a minivan and have some nerve pain and general soreness in my shoulder all the time. Stim really helps relieve the pain and loosen me up. I also use the pads on my calves and back… Rubbing and massage rollers etc work well but stim is the only thing that really releases the tension. Sometimes it takes a few adjustments to get the pads right though! I recommend them!
