Gastrocnemius spasm

Introduction Gastrocnemius tendon, that is, "calf cramps." It is the most common type of painful phlegm. It is characterized by a sudden onset of gastrocnemius muscles, such as tonic, phlegm, and pain, such as twisting. It lasts for tens of seconds to several minutes or more, and its pain is difficult to name. When the arteries harden, the blood circulation in the leg will be blocked, the blood supply will be reduced, and the metabolites will not be taken away in time. When a certain concentration is reached, the muscle contraction will be stimulated, causing pain and cramps, and the blood flow will be reduced after the blood supply is reduced. Local tissue presents with ischemia and hypoxia, and disturbances in physiological and biochemical functions can also cause pain cramps.

Cause

Cold stimulation: When the external environment is cold and humid, such as when the water temperature is too low during swimming, some middle-aged people do not cover the quilt at night.

Excessive fatigue: When traveling long distances or climbing, the calf muscles are most prone to fatigue.

Poor sleep posture: such as prolonged supine, so that the quilt is pressed against the foot, or prone for a long time, so that the foot surface is on the bed, causing the muscles to "passively collapse."

Excessive sleep: causing slower blood circulation and carbon dioxide accumulation.

Calcium deficiency: The calcium content in the blood of middle-aged and elderly people is lower than the normal value, which makes the muscle stress increase.

Symptoms: Turning the tendons, that is, the calfs and tendons are restrained, and the pain is like a twist. It is a common symptom. It is common in both men and women. It often occurs during sleep at night. It is available at four o'clock. Clinically, one or two. Side calves are characterized by sudden convulsions and severe pain. Light for a few minutes, heavy for more than half an hour, massage can ease.

Differential diagnosis

Differential diagnosis of gastrocnemius:

1. Calf muscles after walking: After walking, calf tendon is also a frequent occurrence. Due to excessive walking or running time, the muscles of the lower limbs are overworked.

2. Calf pain: calf pain is caused by a variety of causes of calf muscle soreness, is a symptom of a variety of diseases, usually caused by long-term strain of the calf bones, calcium deficiency, chronic diseases, etc., Chinese medicine is considered to be related to qi deficiency.

3. Calf pain and tenderness in the lower leg muscles: Muscle pain and tenderness in the calf muscles are characteristic features of venous thrombosis. Venous thrombosis is an acute non-suppurative inflammation of the vein accompanied by secondary intravascular thrombosis. The disease formed. The lesion mainly involves the superficial veins of the extremities or the deep veins of the lower extremities. Its clinical features are local swelling and pain of the affected limb, subcutaneous sputum and tender cord or accompanied by venous return obstruction such as superficial varicose veins. Even if the thrombus falls off, it can cause pulmonary embolism.
