Red Ear Syndrome
Red Ear Syndrome is a rare phenomenon characterized by attacks of burning sensations and reddening of one or both ears. This condition has been primarily associated with migraine as well as trigeminal autonomic cephalalgias. Triggers are similar to trigeminal neuralgia and include but are not limited to chewing, temperature changes, gentle touch and/or hair bruising.
As of 2013, there were only 100 documented cases of Red Ear Syndrome and 81% (60/74) of patients reported in the literature with Primary Red Ear Syndrome had a personal history of migraine.1
Temporomandibular disorders, upper cervical spine abnormalities (which are also comorbid with migraine) can cause red ear syndrome.1
