Shingles is a painful cutaneous eruption caused by the varicella-zoster virus.
After being infected by it, the virus remains latent in certain nerves of the body and is reactivated after many years.
Initially, its symptoms are burning or itching that turns into pain. Afterwards, blisters or vesicles that generally follow a linear pattern on the skin appear.
It is diagnosed by medical history and a full physical examination.
There is no treatment to cure the infection of the varicella-zoster virus. Treatment with an antiviral called Acyclovir is applied and its goal is to ease the pain and reduce the number of days in which the patient experiences symptoms.
