question: I am 47 y/o. I take potassium 2 times a day, and never any cramps or swelling. 15 minutes ago, I was sitting at my desk and my abdomen, back, along with my calf and thigh muscles cramped so bad, I became nauseated. I have never had such intense cramping or pain before, and now I am a little scared. It has subsided as of 3-4 minutes ago.
