Cryopyrin-Associated Periodic Syndrome, most often abbreviated to CAPS, belongs to a category of conditions that are genuinely difficult to navigate without precise information. The symptom picture — recurrent fever, an urticarial rash that isn't quite hives, joint pain, fatigue, and systemic inflammation that seems to arise from nowhere — overlaps with dozens of other diagnoses.

Impetigo keeps coming back for some people no matter how carefully they manage hygiene, avoid contact, or finish the prescribed antibiotic course. The sores clear up, life returns to normal, and then a few weeks or months later the familiar crusting and blisters reappear — often on the same child, the same areas, sometimes spreading through the same household.
