Shingles is an infection caused by varicella-zoster virus and it causes a painful rash. This infection can occur anywhere on your body. Most, but not all, people with shingles develop a blistering rash on their body which lasts two to four weeks before a full recovery. You may also observe symptoms like itching, deep pain or burning sensation. The causal viral organism, varicella-zoster virus is the same virus that causes chicken pox and it basically affects the individual nerve and the skin surface that is supplied by the nerve. If you have once recovered from chickenpox, it’s more likely you develop shingles. It is quite not possible to have shingles if you have never been exposed to chickenpox or the causal organism, varicella virus. On exposure, the virus can lay dormant for a number of years and get reactivated later in life. Shingles is actually most common in individuals over the age of 50 years.
