Introduction
Leg numbness during sleep in the supine position may be caused by physiological factors or pathological conditions such as calcium deficiency and lumbar disc herniation. Appropriate treatment should be selected based on the underlying cause. Other potential causes include lumbar spinal stenosis, spondylolisthesis, and spinal tumors. It is recommended to seek timely medical evaluation at a hospital to determine the exact cause and receive treatment as directed by a physician.
Leg numbness during supine sleep may result from physiological factors as well as pathological conditions such as calcium deficiency and lumbar disc herniation. Appropriate treatment should be selected based on the specific underlying cause. The details are as follows:
I. Physiological Factors
If other body parts compress the legs while lying flat during sleep, it may impair blood circulation in the legs, leading to numbness. This is generally a normal phenomenon and does not require special treatment.
II. Pathological Factors
1. Calcium Deficiency
Severe calcium deficiency may lead to nerve dysfunction and vascular spasms, causing peripheral circulatory disturbances and resulting in the aforementioned symptoms. Patients may take medications such as calcium gluconate tablets or tricalcium chewable tablets under medical supervision.
2. Lumbar Disc Herniation
When lying flat, protruding intervertebral discs may compress the sciatic nerve. Moreover, prolonged compression of the sciatic nerve may cause structural damage and partial loss of function, manifesting as leg numbness. Traction therapy can help reduce pressure and irritation on the nerve roots.
In addition to the above causes, other possible conditions include lumbar spinal stenosis, spondylolisthesis, and spinal tumors. It is recommended to seek timely medical evaluation at a hospital to determine the exact cause and follow physician instructions for treatment.
