Periodically, I get leg cramps during the night that can be VERY painful. If I can catch it in time and massage this into my calves, I can usually avoid the cramp all together. But, even if its already cramping, rubbing this on really helps! Its also great for general muscle aches and pains and stiff muscles as well. This is by far the best product I've tried, and I've tried a lot of them over the years! R. O.
