Girls have calf cramps when sleeping at night

Calf muscle cramp: The scientific name of leg cramp is muscle spasm, which is a spontaneous tonic contraction of muscles. Under normal circumstances, the onset of the disease can last for several seconds or tens of seconds. Muscle cramps are most common in the calves and toes and can be extremely painful, especially late at night. Leg cramps in the middle of the night usually wake people up due to the pain, and the pain cannot be relieved for a long time, affecting the quality of sleep. A very simple way is to lift your big toe upwards and stretch your leg straight when the disease occurs.

Causes of leg cramps during sleep

Night-onset leg cramps are associated with

(1) Fatigue: Excessive or vigorous exercise of the feet during the day can cause fatigue. If the muscle tension is not improved at night, the excess metabolic substances cannot be metabolized in time, and its stimulation can cause leg cramps.

(2) Cold: Cold feet and legs during sleep can cause leg muscle cramps.

(3) Hypocalcemia: When the body has low blood calcium, the excitation threshold of the neuromuscular junction is reduced, and the stimulation intensity is significantly lower than that under normal conditions, which can cause neuromuscular excitation. Therefore, it is easy to cause abnormal contraction and cause leg cramps. This condition is common in pregnant women and the elderly who are calcium deficient.

(4) Blood factors: For patients with varicose veins or superficial vein thrombosis in the feet, if they maintain a certain posture for a long time while sleeping at night, the veins in the feet will be stressed and blood flow will be blocked, causing blood stasis. When the blood stasis reaches a certain level, it will cause muscle cramps in the thigh muscles.

Leg cramps during sleep at night diagnosed

Check the condition of leg cramps when sleeping at night

When sleeping at night, the calf muscles may feel uncomfortable or painful, which affects normal sleep. While leg cramps persist, the pain can be very uncomfortable. Leg cramps usually subside automatically within ten minutes, but in severe cases they can cause persistent pain. The ear tapping test (chrostek sign) and the arm compression test (Trousseau sign) were positive, with blood cell calcium less than 2mmol/L and blood cell magnesium less than 0.75mmol/L. Proper treatment can avoid the mistakes caused by a single measurement during medical treatment, thereby achieving a comprehensive assessment of the daytime and nighttime conditions. At the same time, when the patient is stable, dynamic peak velocity meter testing can often indicate changes in the condition.

Identify the cause of leg cramps when sleeping at night

Diagnosis of leg cramps during sleep[1]:

1. Calf cramps: Calf cramps, which are generally called calf cramps in the northern region. Because the contraction of the thigh muscles or the left ventricle during exercise will cause the blood vessels to be squeezed, the blood circulation in the feet will be accelerated, so that metabolic substances can be carried away in time. However, due to many factors, the metabolic substances may accumulate. When it reaches a certain level, it will significantly stimulate the muscles to contract, thus causing leg cramps.

2. Leg muscle cramps after walking: Leg muscle cramps after walking is a common condition. It is mostly caused by walking or running around for too long, resulting in excessive fatigue of the lower limb muscles.

When sleeping at night, the calf muscles may feel uncomfortable or painful, which affects normal sleep. While leg cramps persist, the pain can be very uncomfortable. Leg cramps usually subside automatically within ten minutes, but in severe cases they can cause persistent pain.
