I didn't know that statins caused the cramping I was experiencing, but I did discover Cramp Bark from Herb Pharmacy. As long as I take it 3-5 times a day I have no cramping now for over a year. I had already been taking lots of Calcium, potassium, and magnisium. I am on COQ10 to protect my liver from statins, but will now up the dosage. Cramp Bark is a life saver. I stock pile it!
