I had stunningly painful leg cramps (more like leg jackknifings) when I tried various statins to lower cholesterol. If you're on any medications, check the side effects. A good, experienced pharmacist can review your prescription record to see if you've filled prescriptions for drugs known to trigger leg cramps. There are various forms of magnesium that prevent leg cramps for a lot of people. Also prescription drugs that can help. The best advice is to ask your doctor of course bur leg cramps can usually be alleviated.

I once experienced the same. What I do: get up and take several supplements (calcium, magnesium, and potassium). Then, rub my calf. Now, I’m taking quite a few supplements and rarely feel a twinge. Good luck in your quest for help.
