Relief at last

I suffered from terrible leg cramps from a medical condition. Sometimes I would be up all night with them in excruciating pain. I started applying this during the cramps and within five or six minutes it relieved them, and then I started applying it into the muscles 3 or four times a day and that stopped a lot of of the cramping. Can't recommended enough.
