Do any of these feel familiar?
- Calf cramps are typically experienced as a sudden, involuntary muscle contraction — often described as a violent seizing or locking of the calf muscle — that comes without warning and is extremely painful for its duration
- Cramps most commonly strike at night, waking people from sleep, and may last from a few seconds to several minutes
- The muscle often remains tender and sore for hours or even a day after the cramp resolves
- Many people develop a low-level anxiety about going to sleep or exercising, particularly if cramps are frequent
- Stretching, walking, or pressing the heel down typically brings relief, but the cramp itself is very difficult to prevent in the moment
