Can swimmer's ear go away on its own?
Sometimes it can, but you should not count on it. Swimmer's ear, which doctors call acute otitis externa, is an infection or inflammation of the skin lining the ear canal, the tube between the outer ear and the eardrum. A very mild case, caught on the first day, may calm down within a few days if the ear is kept dry and nothing irritates it further.
The trouble is that a child cannot tell you whether the problem is mild. Early swimmer's ear can look the same as a child who just has water in the ear, and it can move from itchy to painful in a day. The CDC reports that swimmer's ear leads to millions of healthcare visits in the United States each year, and a large share involve children. Most of those families were treated with ear drops.
So the practical answer is a short wait-and-watch window, not a plan to ride it out. If your child has only mild itching or a stuffed feeling and no pain when you gently touch the outer ear, keeping the ear dry for a day or two is reasonable. Anything beyond that deserves a call to the doctor.
What is swimmer's ear, and why does it happen?
Healthy ear canals are lined with skin that is protected by a thin layer of earwax, which is slightly acidic and repels water and germs. When water sits in the canal after swimming, bathing or a splash park, that protective layer softens and the skin becomes damp and irritated. Bacteria, and less often fungi, can then grow on the damaged skin.
Kids who spend hours in the water, swim in lakes or hot tubs, or scratch their ears with fingers or cotton swabs are more likely to get it. Swimmer's ear is not contagious, and it is not the same thing as a middle-ear infection, which sits behind the eardrum and usually follows a cold. Our full guide to preventing and treating swimmer's ear in kids explains the difference in more detail.
How can you tell a mild case from one that needs treatment?
A mild case, in a child who can describe it, usually looks like this: an itchy ear canal, a slightly blocked or full feeling, and maybe a little redness at the opening. There is no fever, no discharge and no pain when you tug gently on the earlobe.
Signs that it has moved past mild, and that the ear is unlikely to clear on its own:
- Pain that grows, especially when the outer ear is pulled, pressed or when the child chews. Pain on tugging the ear is the classic sign of swimmer's ear.
- Swelling of the ear canal, or the ear looking red or puffy.
- Drainage of clear, yellow or pus-like fluid, or a bad smell.
- Muffled hearing from swelling or fluid in the canal.
- Fever, swollen glands in the neck, or redness spreading to the skin around the ear.
Babies and toddlers may not say anything is wrong. Watch for ear pulling, crying that gets worse when lying on the affected side, or fussiness after swimming. Because a young child cannot tell you how much it hurts, a toddler with suspected swimmer's ear should usually be seen sooner rather than later.
How long does swimmer's ear last if you do nothing?
There is no dependable answer, which is exactly why doctors recommend treatment. A very mild irritation can fade in a few days. An established infection can keep worsening, and untreated swimmer's ear can swell the canal shut, make the pain severe, and in rare cases spread to surrounding tissue. Kids with diabetes or weakened immune systems are at higher risk of complications, so they should always be seen.
Once treatment starts, the picture is much more predictable. Most children feel noticeably better within two to three days of starting prescription drops, and a typical course runs about a week. If there is no improvement after two to three days of treatment, the doctor needs to know, because the canal may be too swollen for drops to reach, or the cause may be different.
What should you do while you wait?
If your child has mild symptoms and you are watching for a day or two, these steps help and do no harm:
- Keep the ear dry. No swimming, and cover the ear with a shower cap or a cotton ball coated lightly in petroleum jelly during baths.
- Skip the cotton swabs, fingers and anything else in the ear. They scratch the skin and push debris deeper.
- Dry the outer ear gently with a towel after a bath, and tilt the head so water can drain.
- Use pain relief only as directed by your pediatrician for your child's age and weight.
- Check in daily. If pain, swelling or drainage appear, stop waiting and call.
Avoid home remedies such as hydrogen peroxide, olive oil or alcohol drops unless your doctor says to use them. They can irritate an infected canal, and they are unsafe if your child has ear tubes or a hole in the eardrum. If your child has tubes, read our guide to swimming with ear tubes and call the doctor with any ear pain.
When should you call the doctor or go to urgent care?
Call your child's pediatrician the same day if you see significant ear pain, any drainage, swelling of the ear canal or outer ear, hearing changes, or a fever. Go to urgent care or the emergency room if there is severe swelling, redness spreading across the face or neck, or a stiff neck along with ear symptoms.
A doctor can look into the canal, clean out debris, and confirm that this is swimmer's ear rather than something else. Treatment for children is usually antibiotic ear drops, sometimes combined with a steroid to reduce swelling. Oral antibiotics are generally not needed for uncomplicated cases. If the canal is very swollen, the doctor may place a small wick to help the drops get in. The American Academy of Pediatrics notes that most children respond quickly once treated.
When can your child go back in the water?
Most pediatricians want children to stay out of the water until pain is gone and the course of ear drops is done, which is often seven to ten days. Some will allow swimming earlier with custom ear plugs or a snug swim cap, but follow your own doctor's advice rather than a general rule. Returning too soon is one of the most common reasons swimmer's ear comes back.
When swimming resumes, build a routine that protects the ears every time. Our swimmer's ear prevention checklist walks through drying techniques, and our guide to nose clips and ear plugs for kids covers the gear. Families who swim several times a week should also read our swimmer's ear prevention guide.
If your child is in lessons, tell the instructor about the infection and the return date. Good swim programs are happy to adjust, and a short break is better than a relapse. When you are ready to restart, find swim lessons near you. Swim schools can also use these guides with their own families; see WaterWiseKids for swim schools for ways to partner with us.
How do you stop it from coming back?
Swimmer's ear is largely preventable. Tilt your child's head to each side after swimming to let water drain, dry the outer ears with a towel, and use a hair dryer on the lowest, coolest setting held at arm's length. Avoid cotton swabs. Ask your pediatrician before using any ear-drying drops, since they are not right for every child. Kids who get repeated infections may benefit from ear plugs designed for swimming.

Frequently Asked Questions
Can swimmer's ear go away on its own?
Sometimes. Very mild swimmer's ear, with slight itching and no real pain, can settle in a few days once the ear stays dry. But swimmer's ear is a bacterial or fungal infection of the ear canal, and pain, swelling or drainage usually need prescription ear drops. If symptoms last more than two or three days or get worse, call your child's doctor.
How long does swimmer's ear last without treatment?
There is no reliable timeline, because untreated cases vary. Mild irritation may fade within several days, while a true infection can keep getting more painful and may spread beyond the ear canal. With ear drops prescribed by a doctor, kids often feel better within two to three days and finish treatment in about a week.
Can I treat swimmer's ear at home?
You can keep the ear dry, give age-appropriate pain relief as your doctor advises, and avoid cotton swabs. Do not put drops or home remedies in the ear if your child has ear tubes, a hole in the eardrum, or has had ear surgery. Ask a doctor first, because a child with ear pain needs a proper diagnosis.
Is swimmer's ear contagious?
No. Swimmer's ear is not passed from child to child. It develops when water stays in the ear canal and the skin becomes irritated, which lets bacteria or fungus grow. Sharing a pool does not spread it.
When can my child go back in the water after swimmer's ear?
Ask your doctor, but most children can return to swimming once pain is gone and the course of ear drops is finished, often after about seven to ten days. Some doctors allow earlier swimming with ear plugs or a swim cap. Follow your child's own treatment plan.
