Shingles/Herpes Zoster
What Is It?
Shingles is nerve pain and a rash caused by the varicella-zoster virus (VZV)z, the same virus that causes chickenpox. If you’ve had chickenpox in the past, you could get shingles.
Common Symptoms of Shingles
Symptoms usually affect only a small section on one side of your body and may include:
-
Pain, burning or tingling
-
Sensitivity to touch
-
A red rash that begins a few days after the pain
-
Fluid-filled blisters that break open and crust over
-
Itching
You might also experience symptoms before rash appear:
-
Fever
-
Headache
-
Sensitivity to light
-
Fatigue
Complications
-
Pain that can last for several months
-
Vision may be affected if shingles affects the face
-
Infection of the blisters and the body
-
Death
-
People over the age of 50, pregnant women, and those with weakened immune systems are at risk for complications
Causes
Varicella-zoster virus (VZV) causes shingles. After having chickenpox, VZV stays in your body after your symptoms go away. It hides in your nerve cells inactive (dormant). Sometimes, the virus reactivates later in life, causing shingles.
We aren’t always sure why the virus gets reactivated. But it tends to happen as you get older and your immune system naturally starts to weaken.
Diagnosis/Possible Tests
In most cases, healthcare providers can diagnose shingles by learning about your symptoms and looking at the rash.
Treatment
Shingles is treated with:
-
Antiviral medications.
-
Supportive care.
Antiviral medications are most effective when started within 72 hours of the onset of the rash.
Prevention
-
Get vaccinated if you are in a high-risk group. The vaccine is the best way to protect yourself against shingles
-
Avoid physical contact with someone who is contagious with shingles
When to Seek Immediate Medical Attention
If you have symptoms of shingles, see your healthcare provider right away. Starting antiviral medications as soon as possible can help you feel better faster.
