The term “lumbago” is no longer unfamiliar to elderly people, that is, red herpes around the waist, accompanied by severe paroxysmal lightning-like, tearing-like or pinprick-like pain, can not be touched, clothing can not touch, the pain is particularly severe at night, seriously interfering with the quality of life of patients, so the people called “waist-wrapping dragon”, used to describe the fear of the disease. In fact, this disease is medically known as herpes zoster, and its cause is the invasion of sensory nerves and skin mucous membranes by the herpes zoster virus, accompanied by pain when it is called herpes zoster neuralgia. This disease occurs in elderly patients and is commonly known as the “elderly killer”. In recent years, the incidence of herpes zoster on the head and face has been on the rise in the elderly, surpassing that of herpes zoster on the lower back. The skin changes are dotted or patchy red herpes invading the upper and lower orbits, forehead, temporal, top and occipital areas, most of which occur on one side of the head and face, like a shark biting the head of the eye plate, so called “plate head shark”. The pain is extremely intense, due to the herpes virus invasion of the destruction of the cervical nerve and trigeminal nerve, any “wind blowing to start” or washing the face can trigger paroxysmal stabbing pain, the symptoms are more intense at night, the patient moaning day and night, pain, and even take suicide to get rid of the pain. Experts remind: 1, “Panhead shark” is herpes zoster virus invasion of the head and facial nerves and skin mucous membrane, the nature of the same as the “tangled dragon”, but the pain is more serious, once the herpes and pain, quickly to the pain clinic. 2, early treatment is particularly important, once the best treatment time is delayed, some patients will have lifelong pain, medically known as “postherpetic neuralgia”, is one of the world’s three major intractable pain, treatment is extremely difficult. Nowadays, it is considered to be postherpetic neuralgia if the pain is not relieved for more than half a month. 3, treatment methods: conservative methods include the application of antiviral drugs such as acyclovir, oral antiepileptic drugs such as carbamazepine when accompanied by pain, oral tranquilizers can be used to affect sleep, but conservative treatment is often ineffective. The most effective treatment in the early stage is the use of nerve blocks, which are applied to the nerves invaded by herpes zoster, such as the supraorbital and infraorbital nerves, the supratrochlear nerve, the auriculotemporal nerve, and the cervical 2 or occipital nerves, which can be combined with subcutaneous injections in the lesion area once every 4-5 days, and the majority of patients can be cured in 4-7 times. For patients with poor results of early treatment or who have developed posterior neuralgia, they can be hospitalized for minimally invasive trigeminal or/and permanent destruction of the cervical nerve. 4. Herpes zoster is occasionally secondary to other diseases, such as immune disorders, cervical spine diseases or tumors, and therefore the diagnosis and treatment of the primary disease should not be neglected by focusing only on herpes.
