Treatment of Abscess

Treatment involves incision and drainage. This procedure involves the use of an injectable local anesthetic with subsequent incision of the abscess, allowing it to drain. Frequently, a packing of gauze is left in its place for 1-2 days. The packing is then removed, allowing the abscess cavity to heal (and close) over the course of several weeks. Soapy tub soaks to this area after the packing is removed can help keep the cavity clean. Antibiotics may be indicated in some cases.
