Hypocalcemia: When hypocalcemia occurs in the body, the excitement threshold of the neuromuscular junction is decreased, which is lower than the normal stimulating intensity, which can make the neuromuscular excitatory, and thus can easily cause abnormal contraction and cause calf cramp. This situation is more common in calcium-deficient pregnant women and the elderly.

4, blood flow factors: For patients with leg varicose veins or deep vein thrombosis, if you keep a certain position for a long time when sleeping, leg vein pressure, reflux obstruction, causing blood stasis, when the blood stasis reaches a certain degree, then Can cause paralysis of leg muscles.
