If you’re fact-checking “If you often get leg cramps at night, your body may be trying to warn you about something,” there is some truth behind the headline, but it is more alarming than necessary.

What can you do?
When a cramp strikes, gently stretch the affected muscle, flex your foot upward if it’s a calf cramp, massage the area, or stand and put weight on the leg if you can.

Bottom line: Recurrent nighttime cramps can occasionally be associated with an underlying medical condition or medication, but most aren’t a mysterious warning from your body that something is seriously wrong. The pattern and accompanying symptoms matter much more than the cramp itself.
