Shingles is a viral infection that causes a painful skin rash. It is caused by the same virus that causes chickenpox and is also known as herpes zoster. The virus is dormant in your body if you had chickenpox as a child. Later in life, the virus can reactivate and cause a shingles rash.

Shingles can last from 2 to 6 weeks. Its most common symptoms are rash, pain, fever, sensitivity to light, and fatigue. The rash and fluid-filled blisters form within a couple of days after the onset of pain. It can occur on any part of your body, but typically only affects small areas.

Postherpetic neuralgia occurs when nerve fibers are damaged, resulting in shingles pain that lasts for weeks or months after the rash has cleared.

Ayurveda considers that shingles is a Pitta roga problem, caused by a viral pathogen. Also, the nervous system disorder is caused due to Pitta dosha imbalance.
