Is it common to have bloody mucus with a sinus infection?

It is not uncommon to have bloody mucus with a sinus infection. When the sinuses become inflamed and irritated, the blood vessels in the lining of the sinuses can become congested and leaky, leading to the production of blood-tinged mucus. This is especially common in cases of acute sinusitis, which is a sudden and severe infection of the sinuses. In most cases, the bloody mucus is not a cause for concern and will resolve as the infection clears. However, if the bloody mucus is accompanied by other symptoms, such as severe headache, high fever, or persistent facial pain, it is important to see a doctor to rule out any underlying medical conditions.
