Low-set ears

Low-set ears can indicate genetic conditions such as Down and Turner syndromes, as well as rare syndromes like Shprintzen-Goldberg and Jacobsen.

Creased earlobes

Known as Frank's sign, a diagonal crease in the earlobe may indicate a heart problem. See a doctor if you experience chest pain or shortness of breath along with this symptom.

Single-sided deafness

Single-sided deafness can be caused by trauma, infection, fluid buildup, or acoustic neuroma. If this tumor grows and pushes against the auditory nerve, it can cause hearing loss.

Red ears

If you frequently experience red ears or a burning sensation in the ears accompanied by migraines or cluster headaches, it could indicate Red Ear Syndrome.

Earaches

Adults experiencing earache is rare, but if they do, it could be a type of "referred pain" associated with other conditions like a toothache, TMJ disorder, infection, sore throat, or tumor.
