I wake, almost nightly, with EXTREME leg cramps which typically begin in the inner thigh and radiate from the knee to the lower back. Most often in my left leg, these cramps will bring on uncontrolled screams and cries to God for relief, although I am typically a very reserved person. I wear Dansko shoes because I am on my feet all day, and although I try to avoid too many carbs I am not a true Atkins dieter. I have tried taking OTC potassium supplements, tonic water, pickle juice, orange juice, bananas, and leg cramp pills. I've switched from using regular table salt to a No Salt substitute to increase potassium, and I eat cheese for calcium. Nothing brings relief quickly enough and the exhausted feeling I have the next day is miserable. NOTE: These are not the type of muscle cramps that you simply "walk off" . . . these things have me in absolute agony - ten on the 1-10 scale. What to do?
