I had really suffered immense pain in my back, down my leg and pins and needles in my foot. I had tried osteopaths, chiropractors with scant results. Trying to get a Doctors appointment??? I saw this advertised and thought I would give it a try. Best decision ever! As a dog walker, this has been really hard, I can now walk my 5-7 miles a day, sure I still get the occasional twinge, but I can thoroughly recommend this and have done so to many!
