Shingles is a painful, blistering skin rash caused by the varicella-zoster virus.
After chickenpox has passed, the virus persists inactive in certain nerves of the body and reactivates many years later.
Initially, it manifests with burning or itching of an area of the skin that becomes painful. Subsequently, blisters or vesicles appear, which characteristically follow a linear course.
It is diagnosed by clinical history and complete physical examination.
There is no specific treatment to cure varicella-zoster virus infection. Treatment is prescribed with an antiviral drug called Acyclovir, which is aimed at relieving pain and reducing the number of days of symptoms.
