Why do my legs feel numb when I sleep?

Sometimes people feel soreness and numbness in their legs after going to bed every night, but few people pay special attention to this problem. This will make their condition more and more complicated, and there is no way to completely cure it. It may even make the feeling of soreness and numbness in the legs become more intense, and symptoms of thigh pain may also appear. These are quite common and require regular rehabilitation treatments.

Causes

1. Lumbar disc herniation

Tingling pain in the thigh occurs due to compression of the nerves. If not diagnosed and treated in time, the pain will become more and more severe as the compression becomes more severe, and may eventually affect walking and may cause atrophy of the lower limbs.

2. Local inflammation of the thigh

For example, swollen lymph nodes can also affect limb function in severe cases.

Clinical manifestations

Needle-like pain occurs at the base of the thigh, which lasts for a short time and has no fixed onset time. In severe cases, it may affect walking and may also cause lower limb atrophy, affecting limb function.

examine

1. Lumbar spine X-ray

Degenerative changes such as narrowing of the intervertebral space and hyperplasia of the vertebral margins can sometimes be seen on X-rays, which is an indirect clue. Some patients may have spinal deviation and scoliosis.

2. CT examination

It can clearly show the location, size, shape of the intervertebral disc herniation and the compression and displacement of the nerve roots and dura mater sac. It can also show the thickening of the vertebral lamina and yellow ligament, hyperplasia of the facet joints, stenosis of the spinal canal and lateral recess, etc. It has great diagnostic value for this disease and is now widely used.

diagnosis

Diagnosis is based on history, clinical findings, and examination.

Differential Diagnosis

It should be differentiated from lateral femoral cutaneous neuritis and lateral femoral cutaneous nerve entrapment syndrome causing lateral thigh pain.

1. Lateral femoral cutaneous neuritis

Also known as paresthesia meralgia, the lateral femoral cutaneous nerve is derived from the 2nd to 3rd lumbar nerves, passes through the lateral edge of the psoas major muscle, obliquely passes through the iliacus muscle, along the pelvis through the deep surface of the inguinal ligament, and passes through the lata fascia 10 cm below the anterior superior iliac spine to the thigh skin. During the course of this nerve, if the lateral femoral cutaneous nerve is affected by compression, trauma, or other reasons, lateral femoral cutaneous neuritis may occur. It is more common in obese young and middle-aged men.

2. Lateral femoral cutaneous nerve entrapment syndrome

It is a nerve dysfunction caused by compression of the nerve due to some pressure factors along its route.
