Symptoms

Most muscle cramps develop in the leg muscles, particularly in the calf. Besides the sudden, sharp pain, you might also feel or see a hard lump of muscle tissue beneath your skin.

When to see a doctor

Muscle cramps usually disappear on their own and are rarely serious enough to require medical care. However, see your doctor if your cramps:

• Cause severe discomfort
• Are associated with leg swelling, redness or skin changes
• Are associated with muscle weakness
• Happen frequently
• Don't improve with self-care
• Aren't associated with an obvious cause, such as strenuous exercise
