Leg cramps occur because of involuntary muscle contractions that cause sudden, sharp pain, usually in the calf but sometimes in the thighs or feet. These cramps can happen due to various reasons such as muscle overuse, dehydration, mineral deficiencies (like potassium, calcium, or magnesium), poor blood circulation, nerve compression, or holding a position for a long time. Other contributing factors include aging, pregnancy, medications, and certain medical conditions. Muscle fatigue, especially after intense exercise or in hot weather, can also trigger cramps because the muscles become tired and more prone to involuntary contractions. Stretching, hydration, and maintaining mineral balance are common ways to help prevent leg cramps.
