What are the manifestations of herpes zoster?
Before the occurrence of herpes zoster, local skin may have irritating pain or burning sensation, and occasionally there may be systemic symptoms such as low fever and fatigue. After about1-3 days, dense clusters of small grains of rice to mung bean-sized papules appeared in the painful parts, and the blister wall was tight, and there was a circle of redness around the blister. With the development of the disease, the papules became round herpes, and the flat top was bright. After the blister burst, a clear slurry flowed out. After drying, the scab can become round.
Herpes zoster is mostly distributed in a band, generally along the nerve, on one side of the body, rarely symmetrical. More common in the face and chest, the chest is often distributed along the intercostal nerves, and the lymph nodes in the adjacent areas are swollen and tender.
This disease is a viral infection. If herpes occurs in the cornea, it can form ulcers and even lead to blindness. Herpes virus can invade the brain and cause encephalitis and even paralysis.
Treatment and nursing of herpes zoster
There is no specific drug treatment for herpes zoster, but it can generally heal itself, and the course of disease is about 2 ~ 4 weeks. If secondary infection occurs, it can be treated with antibiotics, hormones and desensitizers, and it can also be used externally with Lufu lotion or calamine lotion. Sulfonamide ointment can relieve itching and prevent secondary infection. Observe the reaction, the effect and the change of body temperature after medication.
When the lesion is on the forehead, it is often accompanied by ophthalmoplegia and ptosis. We should closely observe whether there are any of the above complications. Protect your eyes and prevent keratitis and scleritis. Use chloramphenicol eye drops every day.
In order to stop the pain, traditional Chinese medicine can be applied externally, such as grinding scorpion and centipede and blending with sesame oil, which can clear away heat and toxic materials and have analgesic effect. When applying, you can spread the cleaned old cloth, spread the prepared medicine thinly on the cloth, and then apply the cloth to the affected area, which can be fixed with adhesive tape. When the medicine is dry, it should be replaced at any time until the herpes scabs.
Scratching should be avoided when local herpes and scab occur. Bacterial infection can be secondary after scratching, which will complicate the condition and increase the difficulty of treatment, so it is necessary to cut short the nails of the sick children. Drink more water, expel toxins from the body, increase nutrition and eat a digestible diet.
