Epiglottitis commonly affects children, and it is associated with fever, difficulty in swallowing, drooling, hoarseness of voice, and typically stridor.

The recurrent laryngeal nerve also runs in close proximity to the thyroid gland making hoarseness of voice due to partial paralysis an important side effect of thyroid surgery.

After use with corticosteroid, it is theoretically possible for patients to develop a yeast infection in the mouth (thrush) or hoarseness of voice (dysphonia), although these conditions are clinically very rare.

Specific symptoms treated include: hoarseness of voice, dry cough or productive cough with yellow sticky sputum, sore, dry throat due to heat in the lung and constipation with headache and bloodshot eyes.
