I'm going through the same thing today. I went to the E.R. day before yesterday, all looked perfect, but yes, low calcium, potassium, dehydration and magnesium can all cause it. For me today I think it's due to some dehydration.
Hope you feel better, take a good multi vitamin and eat a couple banana's.
