Shingles is a skin disease or skin infection caused by a virus that lives in nerves system. It is also referred to as herpes zoster. It occurs when the dormant tissue like chickenpox virus, varicella zoster is reactivated in nerve tissue.
This infection will appear in a form of red skin rash, tingling, itching, localized pain and burning sensation. Blistering rash may appear on one side of the body but not for all people with shingles. Typically appearance of shingles or blister can be seen on the torso, neck or face. Shingles usually last from two to four weeks and happens to have complete recovery after that.
Doctors are able to diagnose shingles just from the appearance of the rash. Shingles rarely occurs more than once in the same person, but it may develop approximately 1 in 3 people during their lifetime. However, it may vary from one individual to another where it may reactivate multiple times.
