Leg Cramps at Night: Causes, Prevention, and Treatment
Waking up suddenly with a sharp pain in your leg can be a frustrating and painful experience. Night leg cramps—also known as nocturnal leg cramps—are sudden, involuntary muscle contractions that usually affect the calf muscles, but can also occur in the feet or thighs.
These cramps can last from a few seconds to several minutes and may leave the muscle sore even after the pain disappears.

In many cases, the exact cause is unknown. However, several common factors may increase the risk:
Muscle fatigue or overuse
Dehydration
Mineral deficiencies (such as magnesium or potassium)
Long periods of sitting or inactivity
Poor blood circulation
Certain medications
Pregnancy or aging
Sometimes, underlying health conditions like nerve problems, kidney issues, or diabetes may also play a role.
