Here’s your cheat sheet. Look for pus (yellowish discharge) instead of clear fluid. Check for redness that spreads more than a quarter-inch from the blister. Feel for heat and swelling. And remember: if the blister looks like a tiny volcanic crater with a crust, that’s a warning sign.
If you’re still unsure, listen to your gut. Your body is surprisingly good at telling you when something’s off. Trust that instinct more than WebMD.
One final, gentle truth: most chickenpox spots are just annoying, not dangerous. But an infected one can turn a week of Netflix and calamine into a medical drama. So treat your skin like the precious envelope it is—keep it clean, keep it cool, and definitely keep it unscratched.
