Acute Herpes Zoster (Shingles)

What is Shingles?

Herpes zoster (shingles) is a painful skin rash.

What causes shingles?

It is caused by the varicella zoster virus (VZV), the same virus that causes chickenpox. After a person recovers from chickenpox, the virus stays dormant (inactive) in the body. For reasons that are not fully known, the virus can reactivate years later, causing shingles. Shingles is not caused by the same virus that causes genital herpes, a sexually transmitted disease.

Shingles is most common in older adults and people who have weak immune systems because of stress, injury, certain medicines, or other reasons. Most people who get shingles will get better and will not get it again. But it is possible to get shingles more than once.

Shingles occurs when the virus that causes chickenpox starts up again in your body. After you get better from chickenpox, the virus “sleeps” (is dormant) in your nerve roots. In some people, it stays dormant forever. In others, the virus “wakes up” when disease, stress, or aging weakens the immune system. Some medicines may trigger the virus to wake up and cause a shingles rash. It is not clear why this happens. But after the virus becomes active again, it can only cause shingles, not chickenpox.

You can’t catch shingles from someone else who has shingles. But there is a small chance that a person with a shingles rash can spread the virus to another person who hasn’t had chickenpox and who hasn’t gotten the chickenpox vaccine.

What are the symptoms?

Shingles symptoms happen in stages. At first you may have a headache or be sensitive to light. You may also feel like you have the flu but not have a fever.

Later, you may feel itching, tingling, or pain in a certain area. That’s where a band, strip, or small area of rash may occur a few days later. The rash turns into clusters of blisters. The blisters fill with fluid and then crust over. It takes 2 to 4 weeks for the blisters to heal, and they may leave scars. Some people only get a mild rash. And some do not get a rash at all.

It’s possible that you could also feel dizzy or weak. Or you could have pain or a rash on your face, changes in your vision, changes in how well you can think, or a rash that spreads. A rash or blisters on your face, especially near an eye or on the tip of your nose, can be a warning of eye problems.

What are the treatments for shingles?

The aims of treatment are to limit the severity and duration of pain, shorten the duration of a shingles episode, and reduce complications. Dr. MineHart performs epidural injections depending on where the dermatomes are and subcutaneous infiltration to the actual shingles.
