Shingles, also known as herpes zoster, is a painful skin rash caused by the reactivation of the varicella-zoster virus—the same virus that causes chickenpox. If you’ve had chickenpox, the virus lies dormant in your body and can resurface later as shingles, usually when your immune system is weakened.
Let’s break down the symptoms, complications, and prevention so you can spot it early and protect yourself.
Shingles Symptoms
Symptoms usually appear on one side of the body or face, often as a painful rash. Here’s what to look for:
Early Warning Signs (1–3 days before the rash):
Burning, tingling, or numbness
Itching in a specific area
Fatigue
Fever or chills
Headache
Active Symptoms:
A red rash that turns into fluid-filled blisters
Blisters break open and scab over in 7–10 days
Sharp, stabbing pain in the affected area
Sensitivity to touch or light
The rash typically lasts 2 to 4 weeks, but the pain can linger much longer in some people.
Possible Complications
Shingles isn’t just a rash—it can lead to serious complications, especially in older adults or those with weakened immune systems.
1. Postherpetic Neuralgia (PHN)
Long-lasting nerve pain that persists after the rash has healed
Can last months or even years
Most common complication
2. Vision Loss
