Magnesium is a big factor in cramps - and it is very difficult to get an accurate level with blood tests. I had constant cramps for months and since starting magnesium they are pretty much gone. I had a lot of trouble finding magnesium that would not precipitate nasty diarrhea - but found some awesome stuff on Amazon that works really well and no side effects at all. Angstrom minerals - magnesium. It is a liquid that you put under your tongue for a minute and then swallow the rest - it is absorbed so quickly that it doesn't cause trouble in the digestive system. If you read some of the stuff by Carolyn Dean about magnesium it is fascinating and we are almost all deficient in it because of the depletion in our soil and also our lifestyle. I highly recommend trying this ... I was having really bad cramps in my hamstring and other thigh muscles, even my belly would cramp up if I bent over at too sharp of an angle. I was using magnesium gel which certainly helped with the cramps as they happened but it was hard to measure how much I was getting ... I hope this is helpful.
