Theraworx Relief is the best product out there that I have found that actually works for leg cramps. It starts working immediately when applied to the skin area of a severe muscle cramp. I've never used a product that worked so fast and so efficiently. I started out using Theraworx Relief to stop the pain of active leg cramps and I have recently started using it at bedtime to prevent being wakened by painful leg and foot cramps overnight. This is an excellent product. I can't say enough good about it.
Bottom Line: Yes, I would recommend this to a friend
