Why are my legs always numb?

If a person maintains a posture for a long time, it is easy to cause poor blood circulation in the lower body, resulting in numbness in the legs. However, apart from this cause, if numbness in the legs always occurs, the patient should consider whether there is a problem with the nervous system. Because frequent numbness in the legs is closely related to nervous system diseases, the following article sorts out the specific reasons for leg numbness for readers.

Why are my legs numb?

1. Positional numbness

The reason why squatting or sitting for a long time can cause numbness in the legs is mainly because the blood flow in the lower limbs becomes slow and the nerves are compressed. Generally, just some movement is enough.

2. Peripheral neuropathy

The most common is peripheral neuritis caused by diabetes, which may cause numbness and edema in the distal parts of the lower limbs.

3. Lower limb vascular disease

For example, in occlusive arteriosclerosis, due to hardening of the lower limb arteries, the lumen narrows and leads to insufficient blood supply. The earliest symptoms may include cold limbs, fatigue, numbness or pain.

4. Nerve compression

For example, diseases of the lumbar spine and thoracic spine may also cause numbness of both lower limbs. It is necessary to understand the area of ​​numbness and then identify which nerve innervates the lower limbs. Different nerve segments have different manifestations. Diseases of the cervical spine may compress the nerves and cause symmetrical numbness, pain, and fatigue in the lower limbs. Cervical MRI can detect intervertebral disc herniation, and active treatment can be given after the cause is determined.

Everyone already knows what is going on with numb legs. Now let’s take a look at what to do if your legs are numb:

Change your posture immediately and walk quickly in a small range for a few minutes. If you feel numbness in your left leg, raise your right hand for 10 seconds, then put it down, and repeat 3 times. If your right leg is numb, raise your left hand and the numbness can be relieved. Change your walking posture, such as walking with your eight legs turned inside out, so that different muscles are evenly stressed and the numbness is relieved. Rubbing and applying hot compress to the numb area can also eliminate numbness.

At ordinary times, whether you are standing or sitting, you should maintain the correct posture. Do not maintain the same posture for too long. It is best to change it every few minutes. Do more leg exercises such as jogging and swimming. In addition, diseases such as bone hyperplasia, lumbar disc herniation, and lumbar muscle strain can also affect the peripheral nerves and cause numbness in the legs and feet. If you often feel numbness in your legs and feet, it is recommended to seek medical attention in time.
