has anyone used a personal tens unit for neuropathy? i used my chair massager that pulses quickly in key spots. before i used it i couldn't raise my legs off of the bed. i put the vibrating section under the left side of my very low spine. about thirty minutes later i realized i could lift my leg up without difficulty, still couldn't raise right leg. i have since put the spot under the middle. couldn't lift either at begining, by end i could lift both and get up and off the bed like it was nothing. the effects last up to about two hours. i am going to ask PT tomorrow about it.
