When chickenpox, the virus penetrates and multiplies in the airway and past in the blood then reaches the skin, its main target. There, it induces a characteristic vesicular rash in the form of small droplets. Once the rash is gone, the virus settles in sensory nerve ganglia (spinal posterior, cranial, dorsal roots) where it will remain permanently.
Its reactivation depends on specific factors, the main one being the age and a decrease in the immune system that occurs when the body is suffering from cancer, infection or a neurological disease. Shingles can also occur after radiotherapy or chemotherapy treatment.
Whatever its origin, it always takes the same form: a rash localized (unlike chickenpox, which is General), made of vesicles arranged on reddened skin. These lesions are still on the journey of a sensory nerve. Most often found on the chest or along one or more sides. In addition to its skin annoyances, Herpes Zoster causes severe nerve pain that can either precede, or accompany the eruption, and unfortunately, sometimes persist long after healing. These pains take the form of intense itching, burning sensation. Thus, is shingles easily identifiable! Fortunately, it rarely occurs more than once in the same individual.
Evolution: more harm than fear…
With the exception of the zonas occurring in the very elderly, those involving the ocular nerve (ophthalmic shingles) or those who are spreading in a person whose immunosuppression is major (cancer, AIDS), the evolution of shingles is usually benign. Healing is usually achieved in two to six weeks. Only patience and good treatment will come out of this debilitating condition.
As shingles can reach all parts of the body (arms, torso, back, face), the severity depends on the location of the nervous ride that he decided to follow. When he touches the eye, it can cause damage to the cornea whose consequences are in addition to the eye pain, blindness. Sometimes, the pain persist very long (postherpetic neuralgia). Similarly, the importance of immune deficiency in the appearance of shingles, of any importance whatsoever, told to some doctors that an HIV test is necessary, especially if it occurs in a young person without any apparent reasons.
