Could otitis media (ear infection) go without being treated?

Like before 1940 ?: Some viral ear infections self heal in 2-4 day. Bacterial infections tend to persist and may lead to real complications. Infants need an early eval.If older if not better after 3-4 days, an evaluation and treatment is advised.Prior to antibiotics, hearing loss due to chronic middle ear disease was not uncommon and a significant complication called mastoiditis requires surgical drainage.
