Many years ago, an Asian friend, discovering that I suffered from cramps in my calf ("charlie horses") suggested this treatment. Place your thumb and forefinger of one hand each on one side of those two lines below your nose on your upper lip(this body part may have a name, but I do not know it) and pinch, hard. For about 9 seconds you just feel like a fool and then, magically, the muscles relax. Keep holding for a few more seconds. I assume this technique has to do with accupressure points; I really do not know why it works, but it works for me. Hope it helps you too.
