After treatment, you might develop a sparkly new rash in places you didn’t even itch before. This is called a “post-scabetic” reaction, and it’s basically your skin having a meltdown. Imagine if a tiny army invaded your house, you sprayed them with poison, and then your floors got angry and developed red bumps. That’s your skin.
This new rash is not a sign of failure. It’s a sign that your immune system is burning the village to the ground. However, if that rash includes pustules (pus-filled bumps) or is accompanied by a fever, you might have a bacterial infection. Time to call a doctor—not Google.
