I have an inner ear infection that won t go away. It is greatly painful and I have an emergency appt with an ENT next Monday, but I was wondering what may have caused my infection? I had vomited very forcefully a day or so before my ear started hurting, and some of the vomit had come out my nose on that side and burned a lot. Is it possible bacteria from vomiting started the infection, and if so, does that require special treatment?
