Hello doctor. I have had sinusitis for more than ten years and in the last few days, the weather has changed, I sneeze a lot. This morning, when I blew my nose, there was a lot of blood in it, including clots. Can you give me some advice on how to treat a sinus infection with blood in the nose? I thank you.

Proetz sinus lavage is a fairly common method of sinus lavage. The Proetz procedure helps to remove pus from the sinuses with negative pressure, causing no pain or bleeding during the procedure, suitable for mild cases of sinus disease.
