By the varicella-zoster - zoster virus, the virus generally hidden in the spinal cord dorsal root neurons. When the lower body resistance or fatigue, infection, tumor patients, the virus can re-growth and reproduction, and move along nerve fibers in the skin, so that violations have severe nerve and skin inflammation. Rash are generally based on unilateral and segmental distribution of nerve points, by the cluster component of herpes accompanied by pain. Grow older, the more severe neuralgia.
Symptoms: herpes zoster pain is not light, there is itching, or erythema and no apparent only herpes; severe pain were obvious, sit uneasy bullous skin can occur, blood blisters and even necrosis.
Complications of herpes zoster what?
Herpes zoster occurred in addition to typical clinical herpes zoster skin outside, and sometimes a lot of complications. Although the incidence of complications is not high, but symptoms are often severe and even lead to serious side effects.
1, herpes zoster meningoencephalitis: the virus directly from the spinal cord or nerve root before and after the violation of the central nervous所至up, expressed as headache, vomiting, convulsions, feeling or movement disorders
2, herpes zoster motor root of spinal cord paralysis: the virus before the violations of the root and spinal cord motor neurons, caused by the corresponding parts of muscle weakness or paralysis
3, herpes zoster ophthalmicus: the virus violation of the trigeminal nerve branch所至eyes, the elderly and immunocompromised are more common.
5, herpes zoster oticus: HIV violations and acoustic neuroma facial nerve所至, the performance of the external auditory canal or tympanic membrane for herpes, suffering from the side of paralysis, earache, tinnitus, deafness, dizziness, vomiting, nystagmus,舌前1 / 3 taste disappear nose and palate, such as blisters.
6, neuralgia: nerve-zoster virus and has a strong affinity, after the initial infection (chickenpox or clinical manifestations of occult infection), the virus penetrated the skin of the sensory nerve endings, and along the nerve fibers to the heart of mobile, lasting potential in the spinal cord and dorsal root ganglia. So that ganglion inflammation, necrosis and the emergence of neuralgia. Herpes zoster neuralgia throughout the entire course of disease, and pain of varying lengths of time, age, the more intense the greater the pain, the pain longer postherpetic neuralgia higher incidence.
