Sudden scalp numbness

Many friends will experience scalp numbness when they encounter some scary things in life. This is a normal conduction reaction. However, if the scalp numbness occurs for no reason, then everyone should pay attention. There are many reasons for scalp numbness, such as diabetes, drug side effects, neuritis, etc. If the numbness persists for a long time, you should see a doctor for examination as soon as possible.

What is scalp numbness?

Many people will experience scalp tingling in their lives. This condition can be divided into pathological and physiological conditions. Basically, scalp tingling occurs because of seeing something scary. However, some patients also experience scalp tingling due to medical reasons, such as people who suffer from diabetes. So let us understand what disease scalp tingling is.

First, people with diabetes may experience numbness in their hands and feet. If numbness, soreness, or swelling often occurs in any part of the body, blood sugar should be checked promptly, especially for the elderly.

The second is numbness caused by drugs or chemicals. For example, if you have a cold or diarrhea, taking berberine or furazolidone may cause numbness in your hands and feet. Numbness in your hands and feet may also occur if you stay in an environment containing hydrogen, arsenic, carbon disulfide, etc. for a long time.

The third is numbness caused by neuritis. The most common symptoms of neuritis are numbness of hands and feet, muscle atrophy, and weakness in the limbs. If you have diarrhea or a cold for half a month, it will cause neuritis.

Fourth, numbness occurs scattered in the limbs. Numbness does not occur in the limbs at the same time, but occurs in a scattered manner. This means that local nerves are stimulated, such as a stroke after being drunk, coma causing stimulation of the head nerves, stimulation of the hand nerves by the elderly using crutches, upper limb numbness caused by cervical spondylosis, and leg numbness caused by stimulation of the lumbar shoulder nerves.

Considering that the blood supply to the brain scalp is insufficient, comb your head with a comb (wooden ones are best) before going to bed at night to maintain the blood supply to the scalp and replenish it while sleeping. This will not only cure your scalp numbness, but may also keep your brain awake and enhance brain activity. Also pay attention to keeping warm when sleeping.

Scalp numbness due to blood deficiency and scalp numbness due to phlegm-dampness blocking the meridians: The former is mostly due to excessive blood loss, or insufficient spleen metabolism, or blood and Qi deficiency due to long-term illness, "deficiency of nutrient Qi leads to insensitivity." Blood deficiency causes the skin to lack nourishment, so scalp numbness occurs. The latter is mostly due to fatigue and damage to the spleen, which leads to poor spleen function, internal retention of water and dampness, which accumulates and produces phlegm, which blocks the meridians.
