Our symptom checker will help you find the most suitable treatment for your congested nose or sinus problems.

Nasal congestion and sinus pressure have many causes: colds, the flu, and allergies to name a few. The symptoms of a blocked nose are caused by inflammation and irritation of the nasal passage. In order to flush out the irritation, mucus is produced which can cause sinuses to become blocked. This leads to sinus pressure and pain.
