Thanks for your replies guys.
We've got a Tens machine as my wife used one when she was pregnant, helped her through the labour pains. I've also used it myself for pain relief as I've had two discs done in my lower back and it did help. Trouble is we can't find it - lol!
When we do I'm gonna give it a try and see if it works, just wondered if anyone else had tried it. I'm also unsure where to apply the electrodes/pads, around the area where my sympathetic nerve is or the areas affected. By the way, it's for compensatory sweating as I had ETS surgery a few years back for Planter and Axilla HH.
