Shingles, caused by the reactivation of the varicella-zoster virus, poses several risks and complications. Key issues include intense pain, often described as burning or stabbing, which can persist even after the rash heals (postherpetic neuralgia). Other potential complications are vision loss if shingles affects the eyes, skin infections from scratching, and neurological issues like encephalitis. It’s essential to recognize symptoms early, seek treatment, and consider vaccination to reduce the risk of developing shingles and its complications.
