Can ear infection with fever and no pain or drainage go away on its own without treatment?

If given enough time: and no complications,but, is it an external or middle ear infection?most middle ear infections are viral and don't need an antibiotic, but the complications / secondary bacterial infection may ensue and necessitate therapy.External ear infections are several,can be fungal / bacterial, and the ears and all the body usually clear and rid the infection,but time/other factors may not be in favor

Many do...but...: Most of these, including those caused by bacteria could self heal in a person with a normal immune system. It may take 3 months, but people had them long before we had antibiotics to treat them.However, there are also risks. A complication in that era that is still possible today includes progression to a dangerous infection of the mastoid air cells, behind the ears.

Possible, but also remember that when the outer ear canal is infected, the condition is called Swimmer’s ear, which is different from a Middle ear infection (also a prospect). Some ear infections, such as Middle ear infections, need antibiotic treatment, but many can get better without antibiotics. If symptoms of a Middle ear infection that last for more than 2–3 days, see your Doctor.
