Can cellulitis drain on its own?

Cellulitis affects deeper skin and usually causes spreading redness, warmth, swelling, and pain. Pus or cloudy fluid from a break in the skin can indicate a collection of infection, sometimes called an abscess, rather than simple cellulitis alone. A draining area may still contain infected tissue, and the surface opening does not show how far inflammation extends. Skin redness, skin swelling, and painful skin are useful changes to describe to a clinician.

Do not squeeze, puncture, or try to widen the opening. Wash your hands before and after touching the area, cover it with a clean dressing, and keep surrounding skin clean and dry. Arrange medical assessment promptly so the clinician can decide whether drainage, prescription treatment, or both are appropriate. Mention recent athlete's foot, a wound, or insect bite, and tell them about diabetes if relevant.

Seek urgent help if redness is spreading quickly, pain or swelling is escalating, fever develops, red streaks appear, or you feel faint, confused, or unusually weak. These symptoms can accompany a serious infection such as sepsis and should not be watched at home.

Ask whether the drainage suggests an abscess, how to dress the area, whether a sample is needed, and how you will know treatment is working.
