Calf cramps may be caused by cold, lack of calcium, lumbar disc herniation and other reasons.
1. Cold: If the patient sleeps without a good blanket or the air conditioning temperature is too low, the cold stimulation may cause the calf blood vessels to contract, resulting in spasm of the calf muscles, leading to cramps in the calves.
2. Calcium deficiency: Calcium deficiency will reduce the concentration of calcium ions in the blood, which may lead to abnormal muscle conduction function, muscle nerve over-excitement, resulting in the phenomenon of calf cramps.
3. Lumbar disc herniation: when suffering from lumbar disc herniation, the protruding lumbar disc will press on the nerve root, leading to the innervation of the leg muscle nerve conduction disorders, which may lead to calf cramps.
Calf cramps may have other causes, it is recommended to consult a doctor in time to clarify the cause, and then given by the doctor to standardize the treatment.
