Adult Ear Pain: It’s Not Always an Ear Infection — Here’s What Else It Could Be
When adults come in with ear pain, the assumption is usually “ear infection.” But in adults, ear pain (otalgia) has a wider range of causes than in children — and the source of the pain isn’t always the ear itself. The jaw, throat, teeth, and sinuses can all refer pain to the ear, which is why a physician evaluation matters more than a guess.
I’m Dr. Lisa Clay, board-certified family physician and founder of Monarch Medicine Urgent Care in Carmel. Here are the most common causes of adult ear pain and how I work through the diagnosis.
Common Causes of Adult Ear Pain
Otitis Externa (Swimmer’s Ear)
An infection of the outer ear canal — common after swimming, showering, or using earbuds frequently. Symptoms include pain when pulling on the earlobe, itching, swelling of the ear canal, and sometimes drainage. Treatment is antibiotic ear drops, not oral antibiotics.
Acute Otitis Media (Middle Ear Infection)
Less common in adults than children, but it happens — especially following a cold or upper respiratory infection. Symptoms include deep ear pain, muffled hearing, feeling of fullness, and sometimes fever. Diagnosed by otoscope exam and treated with oral antibiotics when bacterial.
Eustachian Tube Dysfunction
The Eustachian tube connects your middle ear to the back of your throat and equalizes pressure. When it’s swollen — from allergies, a cold, or sinus congestion — you feel fullness, popping, muffled hearing, and dull ear pain. This is the most common cause of ear discomfort in adults during allergy season or after a cold.
TMJ Disorder (Jaw Joint Pain)
The temporomandibular joint sits directly in front of the ear canal. TMJ dysfunction — from grinding, clenching, stress, or arthritis — frequently presents as ear pain. Clues: pain worsens with chewing or jaw movement, clicking/popping sounds in the jaw, and no fever or hearing changes.
Referred Pain from Throat or Teeth
Strep throat, tonsillitis, dental abscess, and wisdom tooth problems can all cause pain that radiates to the ear. If ear pain accompanies a sore throat or dental issue, the ear itself may be fine — the pain is referred from a shared nerve pathway.
Sinus Infection
A sinus infection can cause pressure and pain that radiates to the ear, especially when bending forward or lying down. If ear pain comes with facial pressure, nasal congestion, and thick discharge, the sinuses are likely the primary issue.
Earwax Impaction
A buildup of cerumen (earwax) can cause pain, fullness, muffled hearing, and even dizziness. This is especially common in patients who use cotton swabs (which push wax deeper) or hearing aids. We can evaluate and discuss management options at your visit.
How We Diagnose the Cause
At Monarch Medicine, your physician performs a systematic evaluation:
- Otoscope exam — looking at the ear canal and eardrum for infection, fluid, wax impaction, or perforation
- Throat exam — checking for strep, tonsillitis, or pharyngeal issues that could refer pain
- TMJ assessment — palpating the jaw joint, checking for tenderness with opening/closing
- Sinus assessment — facial tenderness, nasal inspection
- Lymph node exam — checking for swelling indicating infection
- Testing if indicated — rapid strep test, or further workup as needed
This is why a physician evaluation matters for adult ear pain. The cause determines the treatment — antibiotic ear drops for swimmer’s ear, oral antibiotics for middle ear infection, decongestants for Eustachian tube dysfunction, or a dental/TMJ referral for referred pain. A protocol-based retail clinic visit that prescribes amoxicillin for every earache isn’t good medicine.
When to Walk In
Come to Monarch Medicine if you have:
- Ear pain lasting more than 24–48 hours
- Ear pain with fever
- Drainage from the ear (especially blood-tinged or foul-smelling)
- Sudden hearing loss or significant muffling
- Ear pain after swimming or water exposure
- Ear pain with sore throat or sinus symptoms
- Ear pain that wakes you from sleep
Seek emergency care if: You have sudden complete hearing loss in one ear, facial drooping on the side of the ear pain, high fever with severe headache and stiff neck, or significant swelling/redness of the bone behind the ear (possible mastoiditis).
