I have a sinus infection. I keep tasting blood in my mouth. Should I be worried?

Dry nose. If you don't have a frank nosebleed, the taste of blood may be from scant bleeding in your nose in the setting of sinusitis. This may be due to dryness. Humidified air, saline sprays, or saline irrigations may help .
Maybe. I would have the infection treated. But the blood is from the tissue of the nose and sinus cavities being inflammed and "friable" (more likely to bleed).
