What are the early symptoms of snake sores?
| It is a very painful thing to have sores on the body, because sores are completely different from other skin diseases. The impact caused by sores is greater, they can bring greater harm, and the pain of sores is also stronger. They often cause great pain to patients and make them feel very miserable in life. Snake gall sore is a very serious type of sore. Let’s take a look at the early symptoms of snake gall sore. This virus is neurotropic. After invading the sensory nerve endings of the skin, it can move along the nerves to the ganglia of the posterior roots of the spinal cord and lurk there. When the host's cellular immune function is low, such as when suffering from a cold, fever, systemic lupus erythematosus, and malignant tumors, the virus is stimulated again, causing inflammation and necrosis of the ganglia. At the same time, the reactivated virus can move along the peripheral nerve fibers to the skin to cause herpes. In rare cases, the herpes virus can spread to the anterior horn cells of the spinal cord and visceral nerve fibers, causing motor nerve paralysis, such as eye and facial nerve paralysis, as well as gastrointestinal and urinary tract symptoms. Symptoms: Before the onset of the disease, 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. |
