What Is Herpes Zoster? Its Causes, Symptoms, & How to Treat

Herpes zoster, more commonly known as shingles, is a viral infection resulting from the reactivation of the varicella-zoster virus (VZV). This is the same virus that causes chickenpox. While many people may only experience chickenpox during childhood, the virus remains dormant in the nervous system and can reactivate later in life, leading to herpes zoster. This condition is characterized by a painful rash, which can lead to significant discomfort and complications. Understanding herpes zoster, its causes, symptoms, and treatment options is crucial for effective management.
