I should clarify that I dont always have pain with cramping. AS for me I have been worked up completely twice for cardiac and to lesser degree in between by different tests and it is always negative. I have also had the blood testing that was suggested here. When I went back to eating yams it did reduce the incidents and perhaps make them milder. They are high in potassium but also another element that I cant remember that is especially good for cramping/spasming. Blueberries has it too. If I can find it I will post it. Starts with A and is in foods that contain red.
