What does a snake sore look like and what is a snake sore?

Snake sores are simple**: Use good ink and write on the snake sores with a brush. Then draw three circles on the left and three circles on the right.

Lesions are arranged in a band-like pattern along one peripheral nerve, usually on one side of the body, usually no longer than the midline. Neuralgia is a feature of the disease and may precede or accompany skin lesions, often more severe in older patients. The course of the disease is usually 2 to 3 weeks, and the blisters dry up and the scabs fall off, leaving temporary pale erythema or pigmentation.

Before the eruption, there may be mild fatigue, low-grade fever, anorexia and other systemic symptoms, the affected area ** feels burning sensation or neuralgia, and there is obvious pain sensitivity to the touch, which lasts for 1 3 days, and the rash can also occur without prodromal symptoms. The most common sites are the intercostal nerve, cervical nerve, trigeminal nerve, and lumbosacral innervation area. Flushing spots often begin in the affected area.

Soon there are papules the size of miliary to soybeans, which are distributed in clusters without fusion, and then quickly become blisters, the blister walls are tense and shiny, the blister fluid is clear, the periphery is surrounded by redness, and the blister groups in each cluster are normal.

Question 1: Why do I get shingles? How is shingles caused Herpes zoster (also known as loincloth fire pill, snake disc sore, snake pill, loincloth, spider sore, snake string sore, fire sore, flying snake, raw snake, snake loincloth, etc.) is infected by a varicella virus, latent in the body in the posterior root neurons of the spinal cord, usually does not occur, when the immune system declines (long-term illness and weakness, fatigue, cold and fever, anger and other triggers), the virus can grow and multiply again, and move along the nerve fibers to **, so that the invaded nerve and ** produce intense inflammation, Causes clusters of herpes arranged in a band-like pattern along the innervated ** area, accompanied by neuralgia, causing herpes zoster.

Trouble, thanks!

Question 2: How is the snake sores caused Snake sores are herpes zoster, which is a viral disease characterized by the herpes virus (varicella-zoster virus VZV) invading the nerves and causing severe nerve pain in the innervated area and segmental herpes (similar to a band). About more than half of patients with herpes zoster, after the herpes has subsided, there will be long-term persistent pain at the source lesion, that is, postherpetic neuralgia.

**There is a special effect of Zhengyuan pain clearing. In particular, the elderly who are physically weak and those who have herpes zoster who also have chronic systemic diseases have a higher risk of residual posterior neuralgia. 69% of people over 60 years old have post-herpetic neuralgia, and those over 60 years old who have suffered from herpes zoster for more than 3 months have not taken the correct ** post-herpetic neuralgia.

Moreover, a large proportion of elderly patients have neuralgia that can last for months or years, which can seriously affect sleep and mood; The pain is severe and lasts for a long time, which can lead to mental anxiety, depression and other manifestations.

Question 3: What is the cause of snake disc sores caused by decreased immunity.

Snake sores are actually shingles. The main symptom of shingles is pain, followed by a rash, mainly papules and blisters. It can occur anywhere on the body, such as the chest, abdomen, and extremities, and is most severe when the head and face (especially the eyes) are affected.

Typical symptoms. Prodromal phase.

Before the appearance of shingles, some people have systemic symptoms such as fatigue, low-grade fever, headache, etc., and the affected ** may experience abnormal sensations such as burning or pain in advance. These symptoms last for 1 to 5 days.

Typical presentation. After the prodromal phase, the affected ** often appears with clusters of papules and vesicles, the size of which is indefinite, the walls of the vesicles are tense and shiny, the fluid inside is clear, and there is redness on the periphery.

Blisters and other rashes are distributed along unilateral innervated areas, with intercostal nerves, cranial nerves, and lumbosacral innervated areas occurring most commonly. It is typically banded and does not cross the midline of the body to the contralateral side.

The blisters then crust over, usually in 7 to 14 days. All rashes usually resolve within 2 to 4 weeks, but older people take a longer time to resolve. The rash may resolve with temporary erythema, hyperpigmentation, or scarring.

There is usually pain during the rash, which can be dull, convulsive or throbbing, etc., generally paroxysmal, sometimes persistent, and the pain will be aggravated by friction or contact with clothing, and the pain is more obvious in elderly and frail patients. Pain that lasts for at least 3 months after the eruption is called postherpetic neuralgia and is described in detail in the "Complications" section.

Special clinical types.

Including ocular herpes zoster, auricular herpes zoster, abrupt herpes zoster, atherema herpes zoster and disseminated herpes zoster, etc.

Accompanying symptoms. The rash may be preceded by systemic symptoms such as malaise, low-grade fever, headache, and poor appetite.

The rash may be accompanied by: **burning, spontaneous pain, more pronounced pain after touching.

The rash may be accompanied by prolonged, recurrent pain.

Snake sores are herpes zoster, which is caused by viral infection, is a nerve poison, and children's chickenpox is a virus, which is infected with this virus in childhood, latent to the nerve roots, and the onset of herpes zoster when encountering certain triggers in adulthood, which is not the first disease and will not be contagious.

The disease is mainly antiviral**, and antiviral drugs such as acyclovir or ganciclovir can be used. Interferon** may also be used. The pain is unbearable, and you can take analgesics. Acyclovir cream may be applied topically.

"Snake sores" is also known as shingles in medicine. Since the beginning of autumn, the number of patients suffering from "snake sores" has increased, especially the elderly account for a certain proportion. This disease is an acute herpetic disease caused by the varicella-zoster virus, which is caused by a virus ** that is latent in the body.

When the body's resistance is weakened and the immune function is weakened, the herpes zoster virus begins to move, grow and multiply, and spreads along the peripheral nerves, causing a rash, and in severe cases, it can be bloody blisters, which fuse with each other, and necrotic ulcers can also occur, resulting in neuralgia.
