Differential Diagnosis for Shooting Pain in Ear Canal

  • Single most likely diagnosis
    • Earwax impaction or ear canal irritation: This is often the most common cause of shooting pain in the ear canal, usually due to the accumulation of earwax or irritation from inserting objects like cotton swabs into the ear canal.
  • Other Likely diagnoses
    • Middle ear infection (Otitis media): Infections of the middle ear can cause sharp pains, especially if the eardrum is inflamed or perforated.
    • Outer ear infection (Otitis externa): Also known as swimmer's ear, this infection of the outer ear canal can cause severe, shooting pain, especially when the outer ear is touched or pulled.
    • Eustachian tube dysfunction: Problems with the Eustachian tube, which regulates air pressure in the ear, can lead to sharp pains, especially during flights or when experiencing pressure changes.
  • Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
    • Mastoiditis: A serious infection of the mastoid bone in the skull, located behind the ear, which can spread from an untreated middle ear infection. It requires prompt medical attention.
    • Ramsay Hunt syndrome: Caused by the varicella-zoster virus, this condition can lead to facial paralysis and ear pain if not treated promptly.
    • Temporal bone fracture or trauma: Any significant trauma to the head or ear can cause shooting pains and requires immediate medical evaluation to rule out serious complications.
  • Rare diagnoses
    • Trigeminal neuralgia: A chronic pain condition that affects the trigeminal nerve, which can cause sudden, severe, shooting pain in parts of the face, including the ear area.
    • Glossopharyngeal neuralgia: Similar to trigeminal neuralgia but affects the glossopharyngeal nerve, causing sharp pains in the ear, throat, and tongue.
    • Multiple sclerosis or other neurological conditions: In rare cases, shooting pains in the ear can be a symptom of a broader neurological issue, such as multiple sclerosis, though this would typically be accompanied by other neurological symptoms.
