Q.
Angry Red Bump? Why Your Staph Infection Spreads & Medical Next Steps
A.
A rapidly spreading angry red bump is often a staph skin infection that can worsen when bacteria multiply quickly, you squeeze or pick it, treatment is delayed, immunity is low, or the strain is MRSA. Do not squeeze; keep it clean and covered, monitor closely, and seek prompt care if it enlarges, drains, or you develop fever or red streaks, since antibiotics or drainage may be needed; there are several factors to consider, and important details that could change your next steps are explained below.

Q.
Angry Red Bumps? Why Your Pores Are Flaring and Medical Steps to Clear Folliculitis
A.
Folliculitis causes small, itchy red or pus-filled bumps around hair follicles, most often from bacteria, shaving or friction, ingrown hairs, or hot tub exposure. Mild cases often clear with gentle washing, warm compresses, and pausing shaving, but persistent, widespread, very painful, or feverish cases and those in people with diabetes or weakened immunity may need prescription antibiotics or antifungals and sometimes drainage; see below for detailed causes, prevention, look-alikes, and step-by-step guidance that can shape your next care decisions.
