There
are many possible causes of pain in or around the ear although most
patients and even physicians can think of only a few causes. Those
causes being allergies, earwax or ear infection, whether it be a middle ear infection (otitis media) or Swimmer's ear (otitis externa). A few may even think of eustachian tube dysfunction as a possible cause of ear pain. As such, patients are often put on repeated doses of antibiotics, anti-histamines,
nasal decongestants, and nasal sprays. In a certain percentage of
patients, these medications do NOTHING to help with their ear
pain/discomfort. Even tube placement in the ears fail to help. Out of desperation, some patients resort to unproven homeopathic medications listed here.Why does treatment targeting the ear not help? What most people do not realize is that otalgia (medical term for ear pain) may be due to problems totally remote from the ear itself. Indeed, many new parents realize that at least in children, new teeth coming out causes a child to dig or tug on his/her ears, though the ears themselves are completely normal. Indeed, this particular cause of otalgia is due to Cranial Nerve 5 that transmits pain involving the jaw to the ear itself. Sometimes the pain/discomfort is due to a non-biologic trigger, like cell phone use (read more about this here). There are many other examples of non-ear causes of otalgia.
How is it possible that a problem elsewhere in the head and neck causes ear pain??? The main reason is due to referred pain secondary to the numerous nerves that go to the ear from problems found elsewhere in the head and neck. Listed below are the nerves and the most common reasons that produce a particular type of ear pain/discomfort. As one may realize from reading the descriptions, the precise area where the ear pain is felt can lead one to focus on a particular region of the head and neck.
| Nerve | Where Discomfort Usually Felt | Diagnosis of the Ear Pain |
| C2, C3, C4 spinal nerves (Great Auricular & Lesser Occipital Nerve) | Discomfort mainly over the mastoid | cervical spine disc disease (ie, sciatica), whiplash, cervical meningiomas, tendonitis of the sternocleidomastoid muscle |
| Cranial Nerve 7 (Posterior Auricular Nerve) | Discomfort mainly behind the ear | cerebellar pontine angle tumors, geniculate neuralgia |
| Cranial Nerve 5 (Auriculotemporal Nerve) | Discomfort mainly in the front aspect of the ear | TMJ, dental problems, parotid gland tumors/infection |
| Cranial Nerve 9 (Jacobson's Nerve) | Discomfort directly deep in the ear | Tonsillitis, Sinusitis, pharyngeal tumor, adenoiditis, eustachian tube dysfunction |
| Cranial Nerve 10 (Arnold's Nerve) | Discomfort directly in the ear, but more ear canal type pain | GERD (reflux), throat tumors, lingual tonsillitis |
At least 40% of patients presenting to our ENT office with the chief complaint of ear pain is found NOT to have ear infections, but rather some other non-ear issue causing their otalgia. In a primay care office, that number is probably lower.
The most common causes of non-ear otalgia overall are:
- TMJ
- Tonsillitis
- Eustachian Tube Dysfunction
- Throat problems (infection or tumor)
- Cervical Spine Disease
SO, how does one go about figuring out a patient's ear pain if he/she does not appear to have an ear infection on exam? Really, one needs to perform a comprehensive head and neck exam, including examination of the nasal cavity, oral cavity, neck, cervical spine and TMJ. Finger palpation of the tonsil and base of tongue region is a quick and dirty way to figure out hidden oral cavity and throat causes of ear pain. Your ENT may perform fiberoptic endoscopy to more closely examine the nose and throat hidden from direct view. Radiologic exams such as CT or MRI may even be ordered as well.
The key thing to remember, however, is that not all ear pain is caused by ear problems and that pretty much any problem of the head and neck may produce ear pain as a patient's ONLY complaint. Key questions on history that are helpful to guide diagnosis include:
- When did it start?
- How long does the pain last (all the time, a couple hours, a couple seconds, etc)?
- Is it intermittent or continuous?
- What does the pain feel like exactly (sharp, pressure, itchy, burning, etc)?
- Exactly where in/around the ear does the pain occur (deep in ear, behind ear, below ear, etc)?
If a thorough workup by your primary care as well as general ENT has been obtained and still no cause for ear pain has been found, an evaluation by an experienced rheumatologist, neurologist, and neuro-otologist may be the next steps to take.
