Hi Lulu,
I was given one of these machines a couple of years ago to try to help my back pain, unfortuantly it did not work for me but the chronic pain team did tell me that many patients have found some relief with the machine.
I'm going in hospital later on in the year to have a cord stimulation implant fitted which works on the same principle as the TENS, they are hoping it will give me some relief from the trapped nerve in my leg but have said not to get my hopes up for it giving me some relief in the back.
Hope it works for you
