Middle ear infections and inner ear infections might be severe enough to cause hearing loss and other hearing impairments. The middle ear works with pressure, and similar to what happens when your ears are clogged with water, having extra fluids around can impair the normal transmission of the sound. Inner ear infections directly affect the nervous area when hearing impulses are produced and may end up in severe hearing loss. In most cases, hearing acuity goes back to normal after controlling the disease, but this does not happen when there’s irreversible damage to the ear structures. Thus, it is important to give ear infections the importance they deserve and go to the doctor even if they do not cause severe pain.
