    Why is my nose stuffed up (again!!)?The frequent sensation that your nose is blocked-up is quite common – there are millions of fellow-sufferers. Possible causes for that ‘stuffy nose’ feeling include: colds or allergies, unique nasal anatomy, or nasal trauma. Whatever the cause, living with a chronically stuffed-up nose can be frustrating!

    Fortunately, there are new procedures available that offer some sufferers lasting relief without surgery. The NOSE Score helps you determine whether you may be a candidate for one of these procedures by rating the common symptoms:

    • Nasal congestion or stuffiness
    • Nasal blockage or obstruction
    • Trouble breathing through my nose
    • Trouble sleeping
    • Unable to get enough air through my nose during exercise or exertion
