Why does “snake-shaped waist” or shingles appear?

"Snake around the waist" is also known as herpes zoster, which is a viral disease. Its characteristic is that the herpes does not exceed the midline of the body and is more common in the waist. So what factors are related to herpes zoster specifically?

Viral infection.

The direct cause of the disease is infection with the herpes zoster virus. The virus enters the human body through the nasal mucosa and invades the sensory nervous system. It can enter the cortex along the facial nerve and reproduce in the nervous tissue.

Physical reasons

Traditional Chinese medicine believes that the occurrence of shingles is closely related to one's own physical constitution. So, what kind of people are prone to shingles? People with a damp and hot constitution and people with strong liver fire are more likely to develop shingles, because this type of people are usually more irritable and prone to losing their temper. If they have too much anger and too much accumulated depression, it will easily lead to viral infection and shingles. Therefore, we should develop a good habit of being calm and composed, don't be too impatient, and control our emotions.

Traumatic factors.

When the body is injured, damaged by drugs or other infections, the latent virus will rise and move, causing hemorrhagic inflammation of the posterior root nerve nodule on one side, and descending neuritis, which will cause blisters on the skin of the surrounding neuraxial separation area. Due to the low resistance of the patient, the virus in the blisters spreads and causes widespread herpes, which are all causes of shingles. The second type is children who have just had chickenpox, because after the child has had chickenpox, a herpes zoster virus will be produced in the body. This virus will remain dormant in the body and will break out again when the time is right, leading to the appearance of herpes.

The fourth type is transmission among the population.

Because the environment is relatively harsh and there are dense crowds of people, if there is shingles virus, it can be spread in the air through the patient's saliva. And because there are dense crowds of people, the air is generally turbid, which increases the chance of infection. Once the virus enters the skin and mucous membrane tissues of the human body, it will quickly spread throughout the body.
