Chronic nasal congestion can often be caused by chronic sinusitis which is a narrowing of spaces inside your nose and sinuses due to swelling and inflammation. The inflammation may result from infections, autoimmune disorders, or allergies. The condition persists for three months or longer despite receiving treatment.
Chronic sinusitis disrupts your ability to drain mucus, leaving your nose feeling stuffy. You'll have difficulties breathing through the nose, and the area around your eyes might feel tender or swollen.
Also known as chronic rhinosinusitis, this condition affects both children and adults. The condition is often caused by an infection, swollen linings of the sinuses, or growths in the sinuses (i.e. nasal polyps).
