Case vignette: A 24yo M with no past medical history presents with a "boil" on his lower back that he noticed a couple days ago. The boil has been slowly increasing in size and becoming more tender. He denies fever, chills, nausea, vomiting, or history of previous abscesses. On exam there is a 3cm cutaneous abscess with confirmed fluid pocket on ultrasound, and there is minimal surrounding erythema or induration. You decide to incise and drain (I&D) the abscess, including probing to break up loculations and manual decompression, but you are not sure whether you need to irrigate the cavity.
