What can i do to get rid of a stuffynose?

Depends on cause: If your stuffiness is due to an allergy you must either remove yourself from the cause (dog or cat fur, pollen, mold, mites for example) or suppress the bodies reaction to it with prescription or non-prescription meds. Don't use sprays like afrin (oxymetazoline) more than once a day because tolerance develops quickly to these sprays. Occasionally polyps or growths on the lining of the airways develop.
