Sometimes your muscles feel like they're doing the cha-cha without asking. A muscle cramp happens when a muscle suddenly tightens and won't let go, it's like being stuck in a really stiff hug. This can happen because of tired legs, dehydration, or even something you eat before bed.
Examples
- A runner gets a cramp in their calf after sprinting.
- A child wakes up at night with a painful leg cramp.
- Your foot suddenly tightens when you're sitting on the couch.
