Herpes Zoster - Symptoms & Treatment
Somebody who has had chicken pox can extend herpes zoster. Herpes zoster, usually known as shingles, is a viral disease characterized by a tender skin rash with blisters in a inadequate area on one side of the body, often in a stripe.

Many who experience this contamination find it very painful. This acutely painful phase generally lasts several weeks; however, some continue to incident pain or neuralgia long after the outbreak has cleared. This is identified as post-herpetic neuralgia. After primary infection, the virus migrates all along sensory nerve fibers to the satellite cells of dorsal root ganglia where it becomes inactive. This dormancy may be stable, or the virus may become reactivated by conditions of reduced cellular immunity, resulting in herpes zoster. For reasons that aren't completely understood, the virus can become active rather than remaining inactive. When it's activated, it generates shingles. The appearance of active shingles, a history of the typical rash, or old scars from a shingles rash assist a doctor make the diagnosis.
