Greetings. From your history, with recovery from covid - such irritation may occur. This likely involves the sinuses. However, more detailed history like
1. History of elevated blood sugars
2. Whether steroids were used as part of the treatment
3. Oxygen support during treatment
4. Any teeth problem, etc. Would help.
Further sinus evaluation may be needed to identify the problem.
Next Steps
consult online/directly with a nearby ENT specialist with detailed history for proper evaluation and management.
Health Tips
eat healthy food. avoid chilled food items. avoid wet/damp places.
