sudden ear infection child

Overview

A sudden ear infection (also called acute otitis media) is an infection in the middle ear, the small space just behind the eardrum. It often starts after a cold or flu, when fluid builds up and becomes infected. This can cause pain, fever, and sometimes trouble hearing. The pain usually gets worse when the child is lying down.

Yes, ear infections are very common in children. In fact, most children will have at least one ear infection before they turn three years old.

Sudden ear infections mostly affect young children, especially between 6 months and 2 years of age. They are also more common in children who attend daycare, are around cigarette smoke, or who use a pacifier.

Symptoms

Common symptoms

• Ear pain (child may say it hurts or cry more than usual)
• Fever, often around 100.4°F (38°C) or higher
• Feeling that the ear is full or pressure in the ear
• Temporary trouble hearing or muffled sounds
• Fluid or pus draining from the ear (which may bring sudden relief of pain)

Symptoms in children

• Pulling or tugging at the ear
• Fussiness, crying, or being more irritable than usual
• Trouble sleeping or waking up more at night
• Poor feeding or loss of appetite
• Balance problems or clumsiness
• Not responding to sounds as well as usual

Symptoms in older adults

• Although this article focuses on children, older adults can sometimes get ear infections too. If an older adult has ear pain, fever, hearing changes, or fluid from the ear, they should see a healthcare provider.

Causes

Main causes

• Viral infections, such as a cold, flu, or croup, that cause the ear tube to swell and block fluid
• Bacterial infections that grow in the trapped fluid behind the eardrum
• Being around secondhand smoke, which irritates the ear tubes
• Feeding with a bottle while lying flat, which may let fluid enter the ear tube

Risk factors

• Being between 6 months and 2 years old
• Attending daycare or group childcare
• Using a pacifier
• Living with someone who smokes
• Not being breastfed (breastfeeding seems to help protect against infections)
• Having a family history of ear infections
• Having allergies or frequent colds

When to see a doctor

See a doctor urgently if:

• Your child is under 6 months old with any ear pain or fever
• There is pus, blood, or fluid draining from the ear
• Your child has ear pain with a high fever or seems very unwell
• Ear pain lasts for more than 48 hours without improving

Book a routine appointment if:

• Your child complains of ear pain but is otherwise active and comfortable
• You are worried about repeated ear infections
• Your child does not seem to hear well after the infection goes away

Diagnosis

A doctor will look inside your child's ear with a special tool called an otoscope. This lets the doctor check the eardrum for redness, swelling, or fluid. They may also use a pneumatic otoscope that gently puffs air against the eardrum to see how it moves, which helps tell if fluid is present.

Tests that may be done

• Ear exam with an otoscope
• Tympanometry (a small machine that measures how well the eardrum moves)
• Hearing test if ear infections are repeated
• Fluid culture (a lab test) if fluid drains from the ear

What to expect at your appointment

The doctor will ask about your child's symptoms and how long they have been there. The ear exam is usually quick and not painful, although your child may pull away. The doctor will let you know whether the infection is likely viral or bacterial, and discuss ways to manage pain. Unless the infection is severe, the doctor may choose to wait and watch rather than prescribe antibiotics.

Treatment

Treatment focuses first on making your child comfortable. Most ear infections are caused by viruses, so antibiotics do not help and are not usually given. Even bacterial ear infections often clear up without antibiotics, but for some children, especially younger infants or those with severe symptoms, the doctor may recommend antibiotics. Pain relief is the most important part of early care.

Self-care at home

• A warm compress (not hot) held gently against the ear can help soothe pain
• Keep your child well rested and offer plenty of fluids
• Raise your child's head slightly while sleeping (for older children) to help fluid drain
• Over-the-counter pain relief, such as paracetamol or ibuprofen, can be given at the dose your pharmacist or healthcare provider recommends for your child's age and weight
• Never put anything inside the ear, including cotton swabs or eardrops, unless a doctor tells you to

Medical treatments

If the doctor decides to use antibiotics, they will explain why. It is important to give the medicine exactly as prescribed and finish the course, even if your child feels better. The doctor may also recommend pain-relief medicine or, in some cases, eardrops that help with pain. In certain situations, the doctor might refer your child to an ear specialist for further review.

When is surgery considered?

Surgery is not a first treatment for a single ear infection. If ear infections keep coming back, or if fluid stays in the ear and affects hearing, a specialist may suggest placing small tubes in the eardrum to help fluid drain. This decision is made together with you and your healthcare team.

Living with this condition

While your child recovers, offer gentle comfort: hold, cuddle, and speak softly. Keep the home calm and encourage quiet play. Your child may be more tired and irritable for a few days. Keep an eye on their temperature and pain, and make sure they are drinking enough fluids. If your child is old enough, explain that it's okay to cry and that you are going to help them feel better.

Lifestyle tips

• Keep your child home from daycare or school while they have a fever or are clearly unwell
• Avoid exposure to cigarette smoke, which can make ear infections worse
• If your child uses a pacifier, try to wean it after 12 months
• Feed infants in a more upright position, not while lying flat

Diet and exercise

There is no special diet for ear infections, but drinking plenty of fluids helps prevent dehydration, especially if there is a fever. For young children, continue regular feeding or breastfeeding. Once your child feels better, they can return to normal activities as long as they are comfortable.

Mental health and emotional wellbeing

A child in pain can become clingy, irritable, or have trouble sleeping. This is hard on the whole family. It may help to take turns caring for your child so you can rest. Remember that ear pain usually improves quickly, and your child's mood often returns to normal within a few days.

Prevention

You cannot prevent every ear infection, but there are steps to lower the chances: avoid smoking around your child, breastfeed your baby, do not give a bottle while lying down, and wash hands often to reduce colds and flu. Limit pacifier use after the first birthday.

Vaccines

Vaccines can help prevent some infections that lead to ear problems, including the flu vaccine and the pneumococcal vaccine. In the UK, these are offered to children as part of the routine schedule. Talk to your nurse or doctor about your child's vaccinations.

Screening programmes

There is no routine screening for ear infections in healthy children. However, if your child has repeated ear infections or fluid behind the eardrum that lasts a long time, their hearing may be checked to make sure it is developing normally.

Complications

If left untreated

• Fluid in the ear that stays for weeks or months, which can affect hearing
• A burst eardrum (which often heals on its own but needs medical review)
• Rarely, infection spreading to the bone behind the ear (mastoiditis) or to other areas of the head
• Temporary hearing loss, which usually improves when the infection clears

Long-term outlook

The outlook is very good. Most children get better within 2 to 3 days, even without antibiotics. The infection usually clears completely, and hearing returns to normal. Even children with repeated ear infections often outgrow the problem as their ear tubes widen and mature. With good medical guidance and a little patience, your child will likely be feeling like themselves again very soon.
