Introduction
Calf cramps usually refer to leg muscle spasms. Leg cramps at night may be caused by factors such as cold exposure, calcium deficiency, or lumbar disc herniation. Treatment should be based on the underlying cause. Frequently washing feet with cold water or failing to keep the legs warm can lead to muscle spasms in the legs, resulting in cramps. Nighttime leg cramps may also result from excessive fatigue. Patients are advised to stay warm and use comfortable bedding.
Leg cramps at night usually refer to muscle spasms in the calf. Nocturnal leg cramps may be caused by factors such as cold exposure, calcium deficiency, or lumbar disc herniation. Treatment should be based on the underlying cause.
1. Cold Exposure
Frequently washing feet with cold water or failing to keep the legs warm may lead to muscle spasms in the legs, resulting in cramps. Soaking feet in warm water or applying a warm towel compress can improve local blood circulation and promote recovery.
2. Calcium Deficiency
A consistently unbalanced diet may result in insufficient calcium levels in the body, reducing muscle density and triggering leg cramps. Under a doctor's guidance, supplements such as calcium gluconate tablets or vitamin AD drops can be taken to correct the deficiency.
3. Lumbar Disc Herniation
This condition is primarily caused by excessive work or prolonged periods of bending the head forward. During sleep, nerve roots may become compressed, leading to cramps along with symptoms such as limb numbness. A hospital visit for lumbar spine CT or MRI scans is recommended. With professional medical guidance, acupuncture, massage, or other therapies may help relieve symptoms.
In addition, nocturnal leg cramps could also result from excessive fatigue. It is advisable for individuals to maintain warmth, use comfortable bedding, get regular sun exposure, and engage in moderate physical activity.
