Furuncles, also called boils, are another infection that afflicts the hair follicle but originate deeper into the skin than folliculitis. These can become bumpy, pus-filled, and red, and are often warm and tender to the touch. A white or yellow dot may appear at the center, indicating pus that needs to drain. Carbuncles are a cluster of boils that can be a sign of MRSA. These are connected under the skin and can be very painful.
