I've been using Achy Breaky Rub or should I say St Johns Wort & Calendula rub for nearly 10 years now. I have had about 7 spinal operations, 2 laminectomy's, 1 fusion and many many burning back of the nerves in the spine. Nothing has worked. My original operation was in 1976 and I am the product of a surgeon 'slipping' at the critical point. I still have nerve pain in the legs and spine, and as well as restless legs. It seems that Achy Breaky rub really helps - doesn't take all the pain away, but certainly relieves the pain and makes it bearable. I think I've used every product on the market - but I come back to Moon Haven. I know it's pure, smells gorgeous and works.
