Nocturnal leg cramps are sudden contractions of the lower leg and foot muscles. They often awaken you from sleep. The calf muscles are most often involved. The cramps are harmless. They do not mean that you have a serious disease.
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests may include the following:
Blood tests—for hormone or chemical imbalances (most tests are normal)
Checking your foot pulses to assure good circulation
Talk with your doctor about the best plan for you. If no specific cause can be found, treatment options include the following:
When cramps occur, pull against them with your leg muscles. Also, grab your foot (feet) and pull up.
Standing on the affected leg often stops the cramping.
Massage and hot or cold treatments will help the muscles relax.

three times a day and just before going to bed.
Face a wall and put your hands on the wall and keep them there. Step backward. Keep your knees locked. Keep your heels on the floor until you feel a strong pull in your calves. Hold that position for 10 seconds. Repeat two or three times.
Exercise feet and legs regularly.
Drink plenty of liquids.
Eat plenty of potassium-rich foods. This includes bananas, tomatoes, potatoes, broccoli, cantaloupe, oranges, and grapefruit.
