What causes numbness in the lower limbs?

The main causes of numbness in the lower extremities are as follows:

1. Ischemia: After the artery is occluded, the patient will become numb. If the squatting time is too long, or the bending time is too long, numbness will occur, because the squatting or bending time is too long and squeezing, resulting in arterial blood can not reach the soles of the feet, so there is numbness in the lower limbs;

2. Neurological causes: problems with peripheral nerves, such as nerve diseases. There may also be nerve compression, such as compression of the sciatic nerve, or a herniated disc that compresses the nerve root and may also cause numbness.

Once numbness of the lower limbs occurs, vascular disease should be ruled out first, the ankle should be felt first, the dorsalis pedis artery should be checked for pulsation, and if necessary, ultrasound should be done to observe the pulse of the artery. If normal, consider that the numbness may be related to neurological factors. Numbness due to arterial occlusion is a high level of suspicion, and if left untreated, limb necrosis may occur.

The problems in the nerves can be slowed down a little, so after the numbness occurs, we must figure out the cause and the cause.

Secondly, it may be due to numbness in the lower limbs caused by rheumatoid arthritis.

The patient has numbness in the lower limbs, which may be due to the compression of the nerve roots due to the herniated disc in the lumbar spine, and we can make a clear diagnosis through magnetic resonance examination of the lumbar spine, which can be treated by acupuncture and physiotherapy. Some patients may be caused by peripheral neuropathy and need to undergo electromyography and other related tests.

It can be seen in cerebrovascular sequelae, diabetic complications and other diseases. It is mainly manifested as numbness and discomfort on one or both sides of the lower limbs, and some may be accompanied by pain, muscle tonia, spasm, immobility and other symptoms.

It may be that you have not exercised for a long time and your blood circulation is not smooth, so you should exercise appropriately to promote blood circulation.

The main reason for its formation is the degenerative lesion of the intervertebral disc, which rupture the fibrous annulus that has been denatured and weak when bending over or when coughing violently, holding breath, straining to stool and other abdominal pressure, so that the nucleus pulposus protrudes or protrudes and compresses the nerve root, causing symptoms such as low back pain, leg pain, and leg numbness.

The main causes of numbness in the lower limbs include lumbar disc herniation, arteriosclerosis obliterans of the lower limbs, spinal cord lesions and diabetic peripheral neuropathy and other peripheral neuropathy, lumbar disc herniation can compress the nerve roots of the lumbar spine 4-5 or lumbar 5 sacral 1, resulting in symptoms of numbness of the lower limbs, and may also be accompanied by pain and weakness of the lower limbs.

In addition to numbness, arteriosclerosis occlusive disease of the lower limbs can also cause pain, weakness, and intermittent claudication of the lower limbs. Spinal cord diseases can lead to numbness of the lower limbs, including acute myelitis or tumors of the spinal cord, or spinal cord hemorrhage and other causes of spinal cord compression. If the numbness of the lower limbs is caused by diabetic peripheral neuropathy, blood sugar should be actively controlled, and B vitamins should be given to nourish the nerves and lipoic acid**.

Limb numbness refers to the loss of sensation in the limbs. Nutritional deficiency and metabolic limb numbness** mean that the patient may have long-term gastrointestinal dysfunction and indigestion, or have a history of severe nutritional deficiency, resulting in a severe deficiency of vitamin B in the patient's body, resulting in limb numbness; Toxic neurological numbness** is a history of prolonged exposure to heavy metals such as mercury, arsenic, lead, or organophosphorus, or pesticides, as well as chemicals such as furans and isoniazid. This type of chemical can cause toxic neuritis, and the distal limb numbness can occur in the early stage of the disease, often accompanied by pain, **ant walking sensation; Neuritis numbness caused by infection is limb numbness caused by direct invasion of the nervous system by neurotoxins or viruses secreted by bacteria, such diseases mainly include diphtheria neuritis, leprosy neuritis, etc.

Cerebrovascular disease and brain tumors can also cause numbness of the limbs.
