The Bottom Line
Nighttime leg cramps are common and usually harmless.
They may be related to muscle fatigue, prolonged sitting or standing, dehydration, medications, nerve problems, circulation issues, or age-related changes.
The important thing is to watch the pattern.
If cramps become frequent, severe, or appear with swelling, weakness, numbness, or other unusual symptoms, getting medical advice is the safest next step.
