I've been diagnosted with acute otitis media. and the doctor gave me decongestants. antibiotics. and anti inflammatory. when will ne hearing be better?

Ear infection: Even with all that treatment, it takes time for all those things to work and the fluid trapped in your middle ear to resolve. You can also help things along by "popping" your ears, chewing gum. It can take a day or two for the fluid to drain or it can take weeks. Avoid things like strong scents or irritants such as smoke that can cause your body to make even more mucous. Use lots of humidity too!

Soon: Without underlying problems with your ear ventilation tube (eustachian tube), you should be hearing better within a few days to a week.
