What is the difference between nasal congestion and sinus congestion?
That stuffed-up feeling you get when you have a cold or allergy is the result of nasal congestion. The membranes inside the nasal passages become swollen due to inflammation and make it hard to breathe through the nose. If left untreated, it may develop into a more serious problem: sinus congestion. This causes headaches and a feeling of increased pressure in your forehead and around your eyes – particularly when you bend forwards.
