Shingles

Description

It is a viral infection also referred to as herpes zoster, which results from VZV that is the same virus causing chickenpox. This virus may stay in your nervous system for years even if you have recovered from chickenpox infection & reactivate again to cause shingles. In chickenpox, you experience itchy blisters but in shingles, you have a rash with shooting pain.

It appears as a stripe of a blister on one side of the body classically on the torso, face, or neck. It clears in about two to three weeks. Shingles may rarely occur more than once in the same individual.

Causes

It is caused by varicella-zoster virus (VZV) which is the same that causes chickenpox. It will develop in anyone who has had a history of chickenpox. The virus stays dormant in the nervous system for years & reactivate in some cases to travel along the nerve pathway towards the skin & produce shingles. Its exact reason is unknown but may develop due to lower immunity to infections. It mostly in older patients & people with weak immune systems.
