Shingles is a blistering (ampoules) and painful rash caused by the varicella-zoster virus.
The first time a person is infected, the herpes zoster virus causes chickenpox. It remains latent in certain nerves of the body. When the virus is reactivated in these nerves after a period of years, shingles or zoster occurs.
The most common associated symptoms are burning or itching which becomes painful and blisters rash that generally follow a linear pattern on the skin.
It is diagnosed by medical history and a full physical examination.
There is no treatment to cure infection with the varicella-zoster virus. The treatment goal is easing pain and reducing symptom days. There is an antiviral called acyclovir which prevents the virus from replicating, shortening the number of symptom days.
