I'll get right to the point. When you have a cramp in you calf, pinch your upper lip as hard as you can and the cramp will go away - so my mom says.
My mom read this somewhere, tried it, and it worked for her. Wow, did make a fool out of her when we were kids. We joked that of course you won't feel the leg cramp anymore, your lip hurts too much. Either your lip or your ego from looking like a fool....hopping around on one foot while pinching your lip.
I did some research online:
eHow suggests this...
1) Rub your leg and put your leg out straight and flex your foot.
2) Stretch before exercise.
3) Diet - Get plenty of water and calcium, avoid sodium.
4) Take a carnitine supplement
They also agree to rub your leg and watch your diet...then the very last paragraph of the article states:
One pressure point is between and to the front of the space between your big toe and the second toe. Firm pressure with one or two fingers at the onset of cramp will stop it instantly. The other pressure point is the Septum? Which is the lower bone between the nostrils? Firm pressure on this point with the inside of the forefinger at the first sign of lower leg cramp will stop it dead. This last one sounds silly I know but please try it as it nearly always works.
My Personal Research:
Since I'm in the second half of my pregnancy, I have the pleasure of almost nightly leg cramps and get do conduct my own research. Now, the pain usually makes me forget my mother's advice, but after a few seconds I remember and think, "Ah, what they hell, it can't hurt to try". Ladies and Gentlemen, she was right. Within a few seconds the pain slowly goes away and I am able to flex my foot and rub my leg. Thanks mom! You were right....sorry I laughed at you.
