EXPERT INSIGHT

How I assess this in clinic

I first clarify duration, severity, whether symptoms are one-sided or bilateral, and their effect on daily life. I then perform a focused ENT examination and compare the findings with stress, minor trauma or nutritional deficiency may contribute.

Endoscopy or audiometry is not required for everyone. I advise endoscopy when the nose, sinus, throat or voice box needs direct assessment, and audiometry/tympanometry when hearing or middle-ear function is in question.

A common misconception is that every ENT problem needs an antibiotic or an operation. Treatment should instead follow the diagnosis, functional impact, examination findings and evidence-based indications.

Do not wait when: An ulcer lasting over three weeks, a hard edge, bleeding, weight loss or a neck lump needs prompt assessment.
