I bought this machine while suffering the most excruciating sciatica attack I have ever experienced. I was actually bedridden and ended up at A&E where I had to have morphine just so I could be examined. I did not really believe a small device such as sciaticalm could make any dfference but would have tried anything at that stage. I have been using it every day for whole of the month of August and cannot believe how well I am feeling now compared to then. I am free of sciatica for first time in a long time and have even reduced my use of pain killers. I don’t use the belts supplied. I find it easier while lying in bed to just place the device underneath me in the various places I need it. I am so grateful. Thank you Sciaticalm. Mrs Margaret Stelmach.
