Does anybody know if these work. Now and then I get a numbness in my left leg, and if I'm walking when it happens, it's as though I have no control over it - it feels as though my left leg is on a slippery surface. I'm hoping this booster would help me as it could be to do with circulation. Many thanks.
I don't think it has anything to do with circulation. I had a 'trapped nerve' in my back as a result of slipped discs. My left foot sometimes felt as though it was numb and I had to use a walking stick for a while.
