Does it help? My daughter is an advocate of TENS. I have thought I should try it for my back, but not sure I could even place the sensors correctly by myself.
A person at my work recommended a pulsing/hammer type device (same as the chiropractor uses), and I think this could be helpful, as well, but again the challenge of I cannot get behind myself to use one.
TENS Machines do help, but only for a short while.
My wife wants to get one of those hammer machines, too.........................
