OVERVIEW
What Is an Anal Abscess?
An anal abscess is a localized bacterial infection that forms a pus-filled pocket near the anus or rectum, often causing persistent pain, swelling, and fever. Left untreated, the infection can worsen and, in some cases, progress into a chronic fistula. Surgical drainage remains the most effective way to relieve the infection quickly and prevent complications.
CANDIDACY
Who Needs This?
Persistent anal pain, swelling, redness, fever, or a tender lump near the anus usually signals an anal abscess — a bacterial infection that requires prompt surgical drainage, since antibiotics alone are rarely enough to clear it.

Anesthesia
Local, regional, or general anesthesia is administered so the procedure remains pain-free.

Surgical Drainage
The abscess is surgically opened and drained to fully clear the infected fluid.
