Shingles: The Sneaky Virus That Strikes Back
Shingles: The Sneaky Virus That Strikes Back
What's This About?
Shingles is a painful rash caused by the reactivation of the chickenpox virus. It typically affects older adults and those with weakened immune systems.

The Culprit Behind the Rash
Shingles is caused by the varicella-zoster virus, the same virus responsible for chickenpox. After you recover from chickenpox, the virus lies dormant in your nerve tissues. Years later, it can reactivate and travel along nerve pathways to your skin, causing the characteristic shingles rash. This reactivation is more common in people over 50 or those with compromised immune systems.
Recognizing the Signs
Shingles typically begins with pain, tingling, or burning in a specific area of skin. Within a few days, a red rash appears in that area, followed by fluid-filled blisters. The rash usually wraps around one side of your torso or appears on one side of your face. Other symptoms may include fever, headache, and fatigue. If you suspect you have shingles, see a doctor promptly for diagnosis and treatment.
Complications to Watch For
While many people recover from shingles without issues, complications can occur. The most common is postherpetic neuralgia, persistent pain that continues after the rash has healed. Other potential complications include vision problems if the rash occurs near the eye, bacterial skin infections, and in rare cases, inflammation of the brain or spinal cord. Prompt treatment can help reduce the risk of these complications.
FAQs
