I ve been having the smell of blood in my nose and the taste of blood in the back of my mouth. Sometimes when I blow my nose, the mucous is bloody. This worries me. Besides that, it seems like I have other constant sinus problems; sneezing, coughing, headaches, burning eyes, irritated throat, lack of smell and taste, and fatigue. I don t necessarily eat unhealthy or have unhealthy habits, but I never feel any better. What should I do?
