Does Blood in Snot Mean I Have Sinus Infection?

Sometimes, when you have blood in your snot, people worry it might be from a sinus infection. However, blood in the mucus may happen for many reasons. A sinus infection may make you feel congested, have facial pain, or develop a fever. But a little bit of blood can also come from a dry, irritated nose. For example, blowing your nose too hard, allergies, or dry air can cause tiny blood vessels to break. This type of bleeding is typically not a cause for concern. If you have significant bleeding that does not stop despite holding pressure on your nose or if you have other worrisome symptoms, it's important to talk to a doctor to know what is really happening.
