Why pimples form in and around the ear
Oil glands and hair follicles in the bowl of the ear, behind the ear and in the outer third of the ear canal can become blocked with oil, dead skin and bacteria, just like spots elsewhere. Things that trap heat, moisture and bacteria make this more likely:
- Earbuds, headphones, hearing aids or phone use, especially if they are not cleaned.
- Hair products, sweat and not rinsing the ears after exercise.
- Scratching or using cotton buds, which can damage the canal skin.
- Swimming and water trapped in the ear.
- Hormonal changes and a tendency to acne.
What the «pimple» might be
- Acne spot: a whitehead, blackhead or red spot on the outer ear, often with acne elsewhere.
- Boil in the ear canal (furuncle): a very tender lump just inside the ear opening, usually caused by Staphylococcus bacteria. Pain often increases when chewing or when the front of the ear is pressed.
- Folliculitis: several small, itchy or sore spots around hair follicles.
- Epidermoid or sebaceous cyst: a smooth, painless lump behind or on the ear that can become inflamed.
- Infected piercing: redness, swelling and discharge around an earring.
- Spots that are not pimples: a small, painful nodule on the rim of the ear (often from pressure while sleeping), rough sun-related spots, or a sore that does not heal, which should be checked because the ear rim is a common site for skin cancer.
Why you should not pop a pimple in your ear
Squeezing pushes bacteria deeper. In the ear canal, the skin is thin and swelling can quickly block the canal, causing pain and muffled hearing. On the upper ear, infection can spread to the cartilage (perichondritis), which causes a hot, swollen, very painful ear and needs prompt antibiotics to avoid damage to the shape of the ear. Never use pins, tweezers or cotton buds to drain a spot in the canal.
Safe home care
- Apply a warm, clean compress to the outside of the ear for 10 minutes, three or four times a day, to help a spot come to a head and drain on its own.
- Keep the ear dry: avoid swimming and protect the ear when showering until it settles.
- Clean earbuds, headphones, phone screens and hearing aid moulds with an alcohol wipe.
- Wash the outer ear and the area behind the ear gently with mild soap and rinse well.
- Use paracetamol (acetaminophen) or ibuprofen for pain if suitable.
- Acne washes or creams can be used sparingly on the outer ear, but do not put them inside the ear canal.
- Avoid cotton buds; earwax is self-cleaning. See ear wax removal at home.
Boils and infections inside the ear canal
A boil in the ear canal is a localised outer ear infection. When the whole canal is inflamed, red, itchy and painful, often after swimming, the condition is otitis externa, or swimmer’s ear; see swimmer’s ear. Itching from dry skin or eczema can lead to scratching and spots; see itchy ears.
A doctor may prescribe antibiotic ear drops or ointment, oral antibiotics if the infection is spreading, and pain relief. If a boil has formed an abscess, it can be drained safely in clinic. An ENT specialist can also clean the canal under a microscope so that drops reach the skin.
When to see a doctor
- Severe pain, or pain when chewing or touching the front of the ear.
- Swelling that narrows or blocks the ear canal, or muffled hearing.
- Discharge from the ear, or bleeding.
- Fever or feeling unwell.
- Redness and swelling spreading over the ear or to the face, which needs urgent treatment.
- Diabetes, a weakened immune system or older age, because ear canal infections can become more serious.
- A lump that keeps returning or does not go away after two weeks.
- A sore on the ear that does not heal.
Preventing pimples in the ear
- Clean earbuds and headphones regularly and do not share them.
- Dry the outer ear gently after showers and swimming.
- Rinse hair products off thoroughly and keep hair away from the ears when sweating.
- Do not insert cotton buds, fingers or objects into the canal.
- Treat acne and skin conditions such as eczema or seborrhoeic dermatitis.
- Clean piercings and choose hypoallergenic earrings.
Key points to remember
- Pimples in the ear are usually acne spots or small boils.
- Do not squeeze them; infection can spread to the canal or the ear cartilage.
- Warm compresses and keeping the ear dry help most spots settle within a week.
- Severe pain, swelling, discharge, fever or spreading redness need a doctor.
Questions about a pimple in the ear
These answers are general information and do not replace an examination or individual medical advice.
Why is a pimple in my ear so painful?
The skin of the ear is tight and lies directly on cartilage, so even small swelling stretches sensitive tissue.
How long does a pimple in the ear last?
Most settle within a few days to a week. A boil can take one to two weeks and may need treatment.
Can earbuds cause pimples in the ear?
Yes. They trap heat, sweat and bacteria against the skin. Clean them regularly.
Is a pimple in the ear canal dangerous?
Usually not, but it can block the canal and spread. See a doctor if pain is severe or the canal swells shut.
Can I use acne cream inside my ear?
Do not put acne products inside the ear canal. They can irritate the skin and the eardrum.
Could a lump in my ear be something else?
Yes, such as a cyst, a pressure nodule on the rim or, rarely, a skin cancer. A sore that does not heal should be checked.
