(HealthDay News) -- Leg cramps are a common symptom of pregnancy, often occurring at night.

Cramps typically occur only for a short time, but they can be very uncomfortable, the Nemours Foundation says.

The Foundation suggests how to ease the pain and reduce the frequency of cramps during pregnancy:

• Do calf stretches before bed. Make sure not to point your toes while stretching.
• Straighten your leg and flex your foot when you get a cramp. A gentle massage of the calf may relax the muscle.
• Make sure you drink enough fluids.
• If cleared by your doctor, get regular exercise.
