People whose symptoms of a sinus infection do not go away despite the use of antibiotics should follow up with their doctors or ear, nose, and throat specialist quickly.
Call a doctor when experiencing pain or pressure in the upper face accompanied by nasal congestion or discharge, postnasal drip, or ongoing bad breath unrelated to dental problems.
If you experience irritation, pain, blurred vision, redness, or light sensitivity, immediately remove your contact lenses and re-evaluate your symptoms.
