I have Herpes Zoster. In chinese, it's call “生蛇”.I am freaking sad can. It's painful. Zzz. 水痘病毒“苏醒”造成“生蛇” 其实,“生蛇”的医学名称是带状疱疹(HerpesZoster)。“Herpes”源自希腊文,是“爬”的意思,为形容疱疹散布的形式状态。带状疱疹是由水痘带状病毒类型的病毒(Varicella Zoster Virus)长期潜伏在人体内脊髓外侧的神经节内,恢复活动而引发的疾病。患者多数在年幼时曾患过水痘,出现过发烧与全身长满水泡等症状。当水痘痊愈之后,身体上的水泡虽然消失了,病毒却逗留在人体内的知觉神经节里,长期处在“休眠”状态。当人的免疫功能衰弱时,如年老,生病,疲劳,失眠等情况,都可能造成免疫力下降。那些隐藏在神经节内的病毒就开始沿着神经线走,扩散到皮肤上面。 带状疱疹后神经痛”顽固难治 研究显示,在每1000个人口当中,约有3个人会患上带状疱疹。而大约有20%的患者,在带状疱疹痊愈后的6个月,疼痛仍然存在。我们称这为“带状疱疹后神经痛”。治疗这种慢性神经痛非常棘手,因为这种病相当顽固,几乎对每一种疗法都有抗拒性。目前治疗带状疱疹包括服用抗病毒药和止痛药。至于治疗带状疱疹后神经痛,普通的止痛药的疗效不大。治疗神经痛,就要对症下药,必须采用特别的镇痛剂,如抗抑郁药或者抗痉挛药。敷在皮疹上的止痛药膏也很有效用。 如果神经痛得不到舒缓,病患者应该尽早向疼痛治疗专科医生求医。如果疱疹是长在脸上,牵连眼球的巩膜,就会影响到视力,需要看眼科专家了。至于带状疱疹所引起的疼痛,专科医生能够在脊髓硬膜外或末梢内注射止痛药物和类固醇,减少疼痛。目前还有较先进的微创手术专门治难治的带状疱疹后神经痛。这类手术利用微小的刺激器来刺激中枢神经,阻滞疼痛“讯息“从皮肤发送传到中枢神经和大脑。 带状疱疹和带状疱疹后神经痛一般不会有致命危险,但是这种病痛却能够长期折磨病人,严重地影响到生活素质。到目前为止,仍然没有百分百的疗法能够完全止痛。最明智的方法就是注射水痘疫苗,预防患上水痘,从而避免带状疱疹和疱疹后神经痛。 - And so I wiki-ed it. http://en.wikipedia.org/wiki/Herpes_zoster Herpes zoster (or simply zoster), commonly known as shingles, is a viral disease characterized by a painful skin rash with blisters in a limited area on one side of the body, often in a stripe. The initial infection with varicella zoster virus (VZV) causes the acute (short-lived) illness chickenpox, and generally occurs in children and young people. Once an episode of chickenpox has resolved, the virus is not eliminated from the body but can go on to cause shingles—an illness with very different symptoms—often many years after the initial infection. Varicella zoster virus can become latent in the nerve cell bodies and less frequently in non-neuronal satellite cells of dorsal root, cranial nerve or autonomic ganglion,[1] without causing any symptoms.[2] In an immunocompromised individual, perhaps years or decades after a chickenpox infection, the virus may break out of nerve cell bodies and travel down nerve axons to cause viral infection of the skin in the region of the nerve. The virus may spread from one or more ganglia along nerves of an affected segment and infect the corresponding dermatome (an area of skin supplied by one spinal nerve) causing a painful rash.[3][4] Although the rash usually heals within two to four weeks, some sufferers experience residual nerve pain for months or years, a condition called postherpetic neuralgia. Exactly how the virus remains latent in the body, and subsequently re-activates is not understood.[1] Throughout the world the incidence rate of herpes zoster every year ranges from 1.2 to 3.4 cases per 1,000 healthy individuals, increasing to 3.9–11.8 per year per 1,000 individuals among those older than 65 years.[5][6][7] Antiviral drug treatment can reduce the severity and duration of herpes zoster, if a seven to ten day course of these drugs is started within 72 hours of the appearance of the characteristic rash.[5][8] The earliest symptoms of herpes zoster, which include headache, fever, and malaise(malaise-general feeling of discomfortor, uneasiness, an "out of sorts" feeling, often the first indication of an infection or other disease. Malaise is often defined in medicinal research as a "general feeling of being unwell".) are nonspecific, and may result in an incorrect diagnosis.[9][5] These symptoms are commonly followed by sensations of burning pain, itching, hyperesthesia (oversensitivity), or paresthesia ("pins and needles": tingling, pricking, or numbness).[10] The pain may be extreme in the affected dermatome, with sensations that are often described as stinging, tingling, aching, numbing or throbbing, and can be interspersed with quick stabs of agonizing pain.[11] In most cases, after 1–2 days (but sometimes as long as 3 weeks) the initial phase is followed by the appearance of the characteristic skin rash. The pain and rash most commonly occurs on the torso, but can appear on the face, eyes or other parts of the body. At first, the rash appears similar to the first appearance of hives; however, unlike hives, herpes zoster causes skin changes limited to a dermatome, normally resulting in a stripe or belt-like pattern that is limited to one side of the body and does not cross the midline.[10] Zoster sine herpete describes a patient who has all of the symptoms of herpes zoster except this characteristic rash.[12] Later, the rash becomes vesicular, forming small blisters filled with a serous exudate, as the fever and general malaise continue. The painful vesicles eventually become cloudy or darkened as they fill with blood, crust over within seven to ten days, and usually the crusts fall off and the skin heals: but sometimes after severe blistering, scarring and discolored skin remain.[10] I had malaise. I thought it was like that because my stamina sucks. ZZZ. Which still sucks. Okay basically it's not contagious to those who had chickenpox alrdy. For those who hadn't it is. But you get chickenpox and not this. In the western culture. It's uncurable. ZZZ? But in Eastern culture, it is. Okay I am distracted by the pain. Zzz. I found out I had it since ytd cause it's really painful. I thought I sunburn. ... Okay the sun very potent. Can see my sports bra mark. LOL. Still. Pain. Mummy say wait and see how it goes first. She using something to apply on it. Some grass. -.- Grandma say de. PAIN. Fish. |
