Hi, my name is Eve, I get night time muscle cramps in my legs, and feet. It is now 2:AM and I am awake. after having a cramp in my left calf. Dr recommended tonic water with quinine. But I still get the cramps They can come in any part of my legs from the groin down to the toes.. I walk the floor with a cain and cry, they hurt so bad. What causes this and what will help? Thanks!.
