Frequently Asked Questions

Seek immediate care if ear pain is accompanied by sudden hearing loss, severe dizziness or vertigo, or a rash around the ear (which could indicate Ramsay Hunt syndrome). If you have a history of head trauma, or if the pain is accompanied by a high fever and stiff neck, this could signal a more serious infection like meningitis or mastoiditis. Persistent drainage from the ear after an infection has cleared also warrants specialist review to check for a perforated eardrum.
You should seek ENT evaluation if your sore throat lasts longer than 10 days, is accompanied by difficulty swallowing or breathing, or if you have a persistent lump in the neck. ENTs are also the appropriate specialists for recurrent tonsillitis, suspected vocal cord nodules, or unexplained hoarseness lasting more than two weeks, which can be an early sign of laryngeal cancer.
llergies typically cause itchy eyes, sneezing, and clear nasal discharge, and symptoms often correlate with specific triggers like pollen or pets. Sinus infections (sinusitis) usually involve thick, yellow or green mucus, facial pain or pressure, and a reduced sense of smell. If symptoms persist for more than 10 days without improvement or worsen after initial improvement, it is more likely a bacterial sinus infection requiring medical treatment.
Nasal polyps themselves are benign growths, but if left untreated, they can block the sinus drainage pathways, leading to chronic sinusitis and recurrent infections. Over time, this chronic inflammation can cause scarring and structural changes in the sinus lining, making future treatments less effective. In rare cases, large polyps can compress surrounding structures, but they do not turn into cancer. Early management with nasal steroids or surgery can prevent these complications.
