Why do I get cramps in my feet?
Last updated September 3, 2026.
Foot cramps are the small muscles of the arch seizing - driven by overuse, dehydration, low minerals like potassium or calcium, tight shoes, or a new exercise load, and they love the night. Stretching the toes back and standing on the foot end them; hydration and bedtime stretches prevent them. Pymander is a free AI doctor, 24/7 by text, and can help you find your driver.
What to do
- In the cramp: pull toes toward you or stand and load the foot.
- Hydrate daily and around exercise - fluid and salt both matter.
- Stretch calves and feet before bed, and check your shoes are not the culprit.
- Persistent cramps, one-sided swelling, or a new medicine? See a GP.
