Night cramps in the calves or “charley horses,” usually occur at night. These cramps can either prevent someone from falling asleep or may actually wake someone from their sleep. These cramps usually require getting up and “walking the cramps out.”
Frequently, those with night cramps also have unhealthy circulation in the leg’s larger superficial veins. If the leg veins have venous reflux, or backward blood flow in the legs, the blood pools in the leg, especially at the end of the day causing many leg symptoms / conditions, including night cramps. Reflux can be easily detected on ultrasound, and veins can easily be treated. Treating the abnormal veins usually helps improve or even alleviate the night cramps restoring a restful night’s sleep.
