3. Thick Phlegm
The presence of thick phlegm is one of the characteristic signs that appear in most diagnosed cases of sinusitis. Sometimes the phlegm is likely to have a characteristically bad taste or smell and a thick feeling or appearance – and in very advanced cases of sinusitis, it might turn to blood or include small droplets of it.
The presence of the blood can signal complications from blowing the nose too much: This explodes small blood vessels on the inside of the nose. It can be dangerous due to the increased pressure in the sinus cavities this creates – and might lead to additional issues like pain in the ears or a sore throat due to constant irritation.
The phlegm might be one of the worst and most uncomfortable symptoms that you’ll see with sinusitis: The good news is that it can be easy to treat with over-the-counter medications once sinusitis has been diagnosed.
