Leg Cramps

Key Points

Overview

Leg cramps occur when a muscle in the leg tightens suddenly and involuntarily, causing sharp pain. These cramps can last from a few seconds up to 10 minutes and commonly affect the calf muscle, though they can also occur in the feet or thighs. After the cramp subsides, the affected muscle might feel sore for up to 24 hours. Several factors can contribute to leg cramps, including aging, muscle strain from exercise (especially in hot weather), pregnancy, certain medications, and dehydration. Sometimes, the exact cause remains unknown. While most cramps resolve on their own, understanding the triggers can help in managing and preventing them. Management often involves self-care like stretching and massaging the muscle during a cramp. For persistent or severe cramps, a doctor can help identify underlying causes and suggest specific treatments, which may include prescribed exercises or, in some cases, medication.
