Post-herpetic syndrome

There are many common diseases. The treatment method should be selected according to the patient's condition. For serious patients, surgical treatment can be selected, which will be of great help to the stability of the patient's disease. Herpes zoster is a very common disease. Such a disease is very harmful to human health and poses a great threat to the skin. What are the sequelae of herpes zoster?

Many people don't know much about herpes zoster, so after suffering from this disease, they need to undergo a comprehensive examination to have a good understanding of the disease. What are the sequelae of herpes zoster?

Post-herpetic sequelae:

Before the onset of the symptoms of post-herpetic skin, there is burning pain in the local skin, accompanied by mild fever, fatigue, weakness and other systemic symptoms. However, there may be no prodromal symptoms, and scattered erythema may appear on the skin after 1 to 3 days. Subsequently, numerous clusters of papules ranging in size from millet to mung bean appear on the erythema and quickly turn into blisters. The blister wall is tight and shiny, the blister fluid is clear, and there are small depressions on most of the blister surface. After a few days, the blister fluid becomes turbid and purulent, and erosions form after rupture, which finally dry up and form scabs. After the scabs fall off, temporary erythema is left behind. The general course of the disease is about 2 to 4 weeks. Patients with mild symptoms only have erythema and papules, but no blisters, which is called incomplete herpes zoster. Gangrenous herpes zoster may occur in patients with malignant lymphoma, acute systemic lupus erythematosus, and the elderly and infirm, leaving scars after healing, which is called gangrenous herpes zoster. Shingles can spread throughout the body, often accompanied by high fever, pneumonia or encephalitis. In severe cases, if not treated in time, it can lead to death. This is called generalized herpes zoster.

Herpes is mostly distributed on one side, not in a band-like pattern, and sometimes may cross the midline of the trunk. This is due to the nerve endings crossing the midline. The thoracic, cervical and facial trigeminal nerve distribution areas are the most common sites. Usually only one branch of the trigeminal nerve is affected. Local lymph nodes are often swollen and painful. Neuralgia is the main symptom of this disease. The acute phase is due to the inflammatory response of the ganglia, while the late phase neuralgia is caused by post-inflammatory fibrosis of the ganglia and sensory nerves. Sometimes there is severe neuralgia before herpes appears, which is often misdiagnosed as acute abdomen or angina pectoris. Elderly and frail patients or patients with lymphoma often have sequelae of neuralgia, which can sometimes last for several months.

Through the above introduction, we have a good understanding of what the sequelae of shingles are. The above problems will appear after treatment of this type of disease. Therefore, at this time, the patient must be emotionally stable, which will be of great help to the improvement of the sequelae. And elderly patients should pay special attention to this.
