A<unk>  is a cluster of several boils, which is typically filled with purulent exudate (dead neutrophils, phagocytized bacteria, and other cellular components). Fluid may drain freely from the<unk> , or intervention involving an incision and drainage procedure may be needed.<unk> s may develop anywhere, but they are most common on the back and the nape of the neck. A<unk>  is palpable and can range in size to be as small as a pea or as large as a golf ball. The surrounding area is indurated. Later, skin on the centre of the<unk>  softens and peripheral satellite vesicles appear, which rupture discharging pus and give rise to cribriform appearance. As the impending infection develops, itching may occur. There may be localized erythema, skin irritation, and the area may be painful when touched. Sometimes more severe symptoms may occur, such as fatigue, fever, chills, and general malaise as the body fights the infection.
