Shingles is a condition caused by the same virus that causes chickenpox - varicella-zoster virus. It is not contagious by itself; however the virus can spread from a person with shingles to another person and stay in the nerve tissues of the other person for entire life. The virus can then cause shingles to the other person even several years later. A. . . .+
Shingles is also known as herpes zoster. It is an infection of a nerve and the skin around this nerve. It is caused by a virus called varicella-zoster, which also causes chickenpox. According to an estimate, around one in every four people will have at least one episode of shingles during their life.
A common sign that Shingles disease is spreading to the eyes is the appearance of rash on the nose. The virus may then spread from the nose to the eye or nearby area. The cornea of the eye may begin to change its colour and look slightly gray.
The signs and symptoms of shingles mostly affect only a small portion of one side of your body. These signs and symptoms may include such as pain, burning, tingling, red rashes, itching, and fluid-filled blisters. Some people may experience headache, fever, fatigue, and stress. Pain is generally the first and most common symptom of shingles.
The onset of shingles occurs when the herpes zoster virus which causes chickenpox reoccurs in the body. Herpes zoster virus belongs to the herpes viridae family. The virus lies dormant in the nerve system for several years, ever since one has recovered from chickenpox. However, in its inactive state, the individual does not experience any shingles symptoms.
Generally, shingles can be diagnosed with a physical examination of rashes and blisters. Your doctor will ask questions about your medical history. Sometimes, he may ask you for a sample of blood or skin from fluid-filled blisters. He will take the sample on a swab and the sample is tested in a lab.
