12 Symptoms Ear, Nose, and Throat Doctors Say Patients Should Not Ignore
From sudden hearing loss to a persistent sore on the tongue, these are the signs that warrant a visit to an otolaryngologist.

Ear, nose, and throat (ENT) doctors, formally known as otolaryngologists, treat a wide range of conditions affecting the ears, nose, throat, and parts of the head and neck. While some patients see them for recurring sinus infections or thyroid tumors, these specialists also address issues related to hearing, swallowing, breathing, and voice, some of which require urgent medical attention.
Experts emphasize that certain symptoms, even if seemingly minor or painless, should not be disregarded and may indicate serious underlying conditions.
Sudden Hearing Loss
Sudden hearing loss in one ear can be a medical emergency. It might be mistaken for earwax buildup or fluid behind the eardrum, but it could signal sudden sensorineural hearing loss, which affects the inner ear. The sooner this condition is treated, often with steroids, the better the chances of recovery. Immediate medical care is advised if you experience abrupt hearing loss, even if it's accompanied by a feeling of fullness in the ear or follows a cold.
Neck Lumps
A lump in the neck that doesn't hurt can be easily ignored, but pain is not a reliable indicator of seriousness. Such lumps can be enlarged lymph nodes, thyroid nodules, or salivary gland growths. However, some neck lumps can be cancerous. If a new lump appears without a clear cause or persists for more than two weeks, it warrants an examination by a doctor.
Worsening Sore Throat
While a sore throat is common, one that progressively worsens, making swallowing difficult, or is accompanied by muffled speech or an inability to open the mouth fully, could indicate a serious issue like a tonsillar abscess. These can be life-threatening, and if accompanied by breathing difficulties, require emergency care. Prompt evaluation is also needed for worsening throat pain combined with trouble swallowing or speaking normally.
Breathing Pauses During Sleep
If a partner reports that you stop breathing during sleep, followed by gasping and resuming breathing, it could be a sign of obstructive sleep apnea. This condition, where the airway narrows or closes during sleep, can lead to daytime sleepiness and potentially contribute to high blood pressure. Persistent daytime sleepiness and reported breathing pauses during sleep should be discussed with a doctor, potentially leading to a sleep study.
Eye Swelling During Sinus Infection
New swelling around an eye, particularly if accompanied by redness or changes in vision, during a sinus infection should be taken seriously. The thin bone separating the sinus cavity from the eye means infections can rarely spread. If an infection causes pus pockets that need draining to protect vision, urgent medical attention is necessary. Double vision or difficulty moving the eye during a sinus infection requires emergency care.
Jaw Swelling When Eating
Experiencing a tender swelling under the jaw that appears when eating and subsides later can indicate a blocked salivary gland. Eating stimulates saliva production, and a blockage can cause the gland to swell. Persistent swelling, even if it resolves between meals, should be examined to rule out other issues.
Persistent Hoarseness
A voice that doesn't return to normal after a cold or prolonged use, especially if it becomes breathy or loses its projection, needs medical attention. Persistent hoarseness lasting four weeks or more, or sooner if accompanied by other concerning symptoms or in smokers, could be due to vocal cord issues, including thyroid tumors or benign growths. An ENT can examine the vocal cords to determine the cause.
Denture Discomfort
Sudden discomfort or ill-fitting dentures may signal an underlying issue in the mouth, such as an ulcer or a growth on the gum line, that affects how the dentures sit. If a sore under the denture doesn't heal within two weeks, it should be examined by a dentist to rule out conditions like oral cancer.
Unstoppable Nosebleeds
While most nosebleeds can be managed with pressure, persistent or heavy bleeding, especially if it feels like blood is draining down the back of the throat, might indicate a posterior nosebleed. Heavy bleeding, weakness, or lightheadedness after a nosebleed requires emergency care. Recurrent nosebleeds, even if they stop, should be reported to a doctor, as they can sometimes be a sign of a tumor inside the nose.
Ear Pain Without Apparent Cause
Ear pain that persists despite a normal ear examination may originate from elsewhere. Nerves can transmit pain signals from other areas, such as the jaw joint, throat, or the base of the tongue, to the ear. If ear pain continues without an identifiable ear issue, especially if swallowing is painful or a neck lump is present, further investigation is warranted.
Persistent Blocked Nostril
A nasal blockage that affects only one nostril and persists longer than a typical cold may be concerning. While a deviated septum is a common cause, a growth inside the nose or sinuses could also be responsible. If one nostril repeatedly bleeds or remains blocked beyond the expected duration of a cold, it should be evaluated.
Non-Healing Tongue Sore
A sore on the tongue that does not heal within one to two weeks, grows, or becomes increasingly painful, particularly on the side of the tongue, warrants medical attention. Such persistent sores, even after negative initial biopsies, could be an early sign of tongue cancer and should be thoroughly evaluated by a specialist.
