Initially, nasal packs may be uncomfortable because you will be forced to breathe through your mouth, causing dryness. Your sense of smell and taste may also be temporarily impaired.
You may have some thin bloody secretions within the first few hours that may drain down the back of your throat or out your nose. Thin bloody secretions are normal and should not be confused with thicker active bleeding. Once a pack is placed, the irritated nose will secrete thin mucus that may become blood-stained because of the dry clotted blood within the nasal pack.
You may be prescribed antibiotics to prevent sinus infections — take the medication as prescribed.
