I will occasionally have calf cramps at night. Usually my left leg. I wake up and flex my foot, and my calf seizes up. Actually the calf itself is not as tight as the muscle right on the outside edge. Looking that up, it seems to be the Fibularis Longus. My foot sometimes cramps at the same time. It eases up after a minute or so. It hasn't happened in a while.
the hands that guide me are invisible
