And my first thought when you said that the antibiotics were not completely working was that she might have accidentally breathed something in and it set up an infection, like you said.. 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.
