On March 29, 2007 I was feeling itchy on my left collarbone area and thought nothing of it. Then after lunch, I was feeling itchy on my left shoulder. I thought back to what I ate, but I didn't eat anything which I didn't eat before. I made an appointment to see my primary care physician and tried to hold off on itching :(
At the doctor's office, it was diagnosed that I had shingles.
From the wiki encyclopedia:
Herpes zoster, colloquially known as shingles, is the reactivation of
varicella zoster virus (one of the
Herpesviridae group), leading to a crop of painful
blisters over the area of a
dermatome.
Signs and symptoms
The earliest symptoms of shingles include headache, sensitivity to light, flu-like symptoms without fever, as well as itching, tingling, and extreme pain where the rash is developing. Often,
pain is the first symptom. This pain can be characterized as stinging, tingling, numbing, or throbbing, and can be pronounced with quick stabs of intensity. Then 1-3 crops of red lesions develop, which gradually turn into small
blisters filled with
serous fluid. A general feeling of unwellness often occurs. In some cases, the rash does not form blisters, but has an appearance much like
urticaria ("hives").
Shingles cannot be passed from one person to another. However, the virus that causes shingles, VZV, can be spread from a person with active shingles to a person who has never had chickenpox through direct contact with the rash. The person exposed would then develop chickenpox, not shingles. The virus is not spread through sneezing, coughing or casual contact. A person with shingles can spread the disease when the rash is in the blister-phase. Once the rash has developed crusts, the person is no longer contagious. A person is not infectious before blisters appear or with post-herpetic neuralgia (pain after the rash is gone).
Chickenpox virus can remain dormant for decades, and does so inside the
ganglion near the spinal cord. As the virus is reactivated it spreads down peripheral nerve fibers and produces intense pain. The blisters therefore only affect one area of the body and do not cross the midline. They are most common on the torso, but can also appear on the face (where they are potentially hazardous to vision) or other parts of the body.
Outbreaks occur for many different reasons, most of which are a result of events which decrease the immune system such as aging, severe emotional stress, severe illness or long-term use of corticosteroids.
