Ear, nose and throat symptoms are common and may occur due to infections, allergies, irritation, or changes in the surrounding environment. Some symptoms improve with rest or basic care, while others may continue, return frequently, or affect daily activities.
An ENT specialist, also known as an ear, nose and throat specialist or otolaryngologist, assesses conditions affecting the ears, nose, throat, head, and neck. Knowing when to seek medical review may help identify possible causes and guide appropriate care.
Ongoing Nasal Blockage
A blocked nose may occur during a cold, allergy flare-up, or sinus infection. However, nasal blockage that continues for weeks or keeps returning may need medical assessment.
Possible causes include allergic rhinitis, sinusitis, nasal polyps, enlarged turbinates, or a deviated nasal septum. An ENT specialist may examine the nasal passages to assess whether the blockage is related to inflammation, allergy, infection, or structural factors.
Frequent Sneezing, Runny Nose, or Post-Nasal Drip
Sneezing, watery nasal discharge, itchy nose, and post-nasal drip may be signs of allergic rhinitis. In Singapore, common triggers may include dust mites, mould, haze, and air-conditioned environments.
If these symptoms affect sleep, concentration, work, or school, an ENT doctor may help assess the cause and discuss suitable management options.
Recurrent Sinus Symptoms
Sinus-related symptoms may include facial pressure, blocked nose, thick nasal discharge, headache, reduced sense of smell, and post-nasal drip. Some symptoms may occur after a cold, while others may recur over time.
You may consider seeing an ENT specialist if sinus symptoms are frequent, long-lasting, or associated with facial discomfort or smell changes.
Ear Pain or Ear Discharge
Ear pain may be linked to ear infections, earwax blockage, eardrum issues, jaw joint problems, or referred pain from the throat. Ear discharge may suggest infection or irritation in the ear canal or middle ear.
Medical review may be needed if ear pain is severe, recurrent, or associated with discharge, fever, dizziness, or hearing changes.
Hearing Loss or Blocked Ear Sensation
A blocked ear sensation may be due to earwax, infection, fluid behind the eardrum, pressure changes, or Eustachian tube dysfunction.
Sudden hearing loss should be assessed promptly. For gradual or recurring hearing symptoms, an ear nose throat specialist may recommend evaluation and hearing tests where appropriate.
Ringing or Buzzing in the Ear
An ENT doctor may assess tinnitus, especially if it is one-sided, associated with hearing loss, dizziness, ear pressure, or changes in balance.
Dizziness or Balance Problems
Some dizziness and balance symptoms may be related to the inner ear. Patients may experience spinning sensations, nausea, unsteadiness, or dizziness triggered by head movement.
As dizziness can have many possible causes, medical assessment may help determine whether the symptoms are related to the ear, balance system, medication, circulation, or other health factors.
Recurrent Sore Throat or Tonsil Problems
A sore throat may be caused by viral infections, bacterial infections, allergies, reflux, dryness, or irritation. Tonsil problems may cause throat pain, fever, bad breath, swollen glands, or discomfort when swallowing.
An ENT specialist may assess recurrent tonsillitis, frequent throat infections, or throat symptoms that do not settle.
Hoarseness or Voice Changes
Hoarseness may occur after a cold, voice strain, acid reflux, smoking exposure, or irritation of the vocal cords. It may also affect people who use their voice regularly for work.
Voice changes that continue, recur, or occur with throat discomfort, swallowing difficulty, breathing symptoms, or a neck lump should be medically assessed.
Snoring or Sleep-Related Breathing Symptoms
An ENT doctor may assess whether the symptoms are related to the nose, throat, or upper airway.
Swallowing Difficulty or Throat Discomfort
Difficulty swallowing, pain when swallowing, frequent choking sensation, or a feeling of a lump in the throat may have several possible causes. These may include reflux, infection, muscle tension, inflammation, or other throat conditions.
Medical review is advisable if swallowing symptoms persist, worsen, or occur with weight loss, voice changes, breathing symptoms, or neck swelling.
Nosebleeds That Recur
Nosebleeds may occur due to dryness, nose picking, irritation, trauma, infection, or blood vessel sensitivity. In some cases, they may also be related to medication or other medical factors.
An ENT specialist may assess recurrent nosebleeds, heavy bleeding, or bleeding that occurs without a clear trigger.
ENT Symptoms in Children
Children may need ENT assessment for recurrent ear infections, hearing concerns, persistent blocked nose, mouth breathing, snoring, enlarged tonsils or adenoids, and repeated throat infections.
Parents may notice signs such as poor sleep, loud snoring, delayed response to sounds, frequent ear pulling, nasal-sounding speech, or difficulty concentrating in school.
