what caues painful cramps or muscle spasms in the thighs

Okay, I have this too, but went to the chiropractor today and was told it is a deficiency of magnesium and potasium, and I am dehydrated.  So, recommending Ionic Fizz by a company called Pure.   It is found at health food stores and apparently can immediately stop the leg cramp pain.  Trying it right now.

I take magnesium every day. I has helped my migraines tremendously. I drink lots of water. None of it helps. I still get the inner thigh spasms. Have been dealing with it for 2 weeks now. This time it is just not going away. My muscle relaxers aren't even working this time.
