Symptoms

Sudden tight pain in the calf or foot, often at night in the second or third trimester.

What may help

Gentle calf stretches before bed.
Stay hydrated; balanced electrolytes from food.
Foods with magnesium: pumpkin seeds, spinach, bananas, whole grains (as part of normal diet).
Comfortable shoes; avoid standing too long.

Notes

Persistent swelling with headache or vision changes is not a simple cramp — seek urgent care for possible preeclampsia screening.
