SymptomsBy Mayo Clinic staff
Most muscle cramps develop in the leg muscles, particularly the muscles in the calf. In addition to the sudden, sharp pain, you may also be able to 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
