An earache is often a middle ear problem: fluid or infection behind the eardrum. The canal outside the drum is a different infection. That one is swimmer's ear.
How the middle ear gets sick
The eustachian tube connects the middle ear to the back of the nose and keeps air pressure even on both sides of the eardrum. A cold, sinus infection, or allergy can swell that tube shut. Air in the middle ear is absorbed, fluid collects, and bacteria or viruses from the nose can infect it. That is otitis media.
Children get this more often. Their tubes are shorter and sit at an angle that drains less easily. Pain, fever, muffled hearing, irritability, poor sleep, and tugging at the ear are the usual clues. If the drum tears, you may see drainage, and the pain often eases once pressure is gone. Most small holes from a single infection close. Read holes in the eardrum if drainage continues.
What the visit includes
We look at the drum and ask how long the pain and fever have lasted. A hearing test measures how much sound is getting through. A tympanogram measures how the drum moves when pressure changes, which tells us whether fluid is still sitting behind it.
A bacterial infection is treated with an antibiotic for the full course, then a follow-up so we know the ear cleared. Viruses do not need an antibiotic. Pain can be treated while the infection settles. If a cold or allergy is keeping the tube blocked, that gets treated too. Decongestants are not right for every child. Ask before you start one.
When infections keep returning
Many ears recover with medicine and time. If fluid or infection keeps returning, or hearing stays down, we talk about a small ventilation tube placed through the drum. The tube lets air in and fluid out while the eustachian tube recovers. It is a short procedure. The tube usually works its way out months later.
Allergy can sit underneath repeated ear fluid. If that fits the history, allergy care is part of the plan, not a separate problem.
Call if pain, fever, or drainage is not improving, or if a child is hard to console. Ear infections are part of our ear, nose, and throat care.
