Sometimes the walls of an abscess are very tough and makes it harder for antibiotics to 'get through' If it is an abscess that's easily reached, then the usual treatment is to drain it first, and also give antibiotics. But with her abscess
in this location, that's not as easy. Usually for a lung abscess
, antibiotic treatment is used, and drainage only occasionally, but that does depend on what is stuck down there. A bronchoscopy might be the answer.
