What is shingles and how do you get it?

Shingles is not caught - it is awakened. After childhood chickenpox, the varicella-zoster virus retreats into nerve roots and sleeps there for decades, held down by immunity. When immunity dips - with age, stress, illness, or immune-suppressing medications - the virus can reactivate, traveling down one nerve to the skin: the classic presentation is a painful, burning, one-sided stripe of blisters following the nerve's territory, often wrapping one side of the torso or one side of the face. NIA and CDC guidance note the telltale signs: pain, tingling, or burning often arrives days BEFORE the rash, then fluid-filled blisters that crust over two to four weeks. The complication to fear: postherpetic neuralgia - nerve pain persisting months to years after the rash heals - which climbs steeply with age and is the main argument for the Shingrix vaccine at 50-plus. The eye is the urgent zone: shingles on the forehead or near the eye can damage vision - same-day care. Can you catch shingles from someone? No - but a person with shingles blisters can transmit the virus to someone who never had chickenpox or the vaccine, giving them chickenpox, until the blisters crust. Early antivirals - within 72 hours of rash onset - shorten the course and cut the nerve-pain risk, which is why a same-week call matters. Pymander is a free AI doctor, 24/7 by text.
