Facts on muscle cramps and how to stop them from Cleveland Clinic

Cleveland Clinic says muscle cramps—often called spasms—strike unpredictably, ranging from a “charley horse” in the leg to tightness in the back, arms, neck, chest, abdomen, and ribcage. A cramp happens when a muscle contracts forcefully and can’t release, causing pain as the tightening grabs attention immediately. The organization notes anyone can get a cramp at any time, including during a walk, while sitting, during workouts, or at night. It emphasizes that no method reliably stops every episode, but prevention and relief steps can help.
