I am in the same boat I take mucinex D and NyQuil at night that is the only thing that helps my nose and my sinuses. I had catscan with chronic sinusitis. Omg head feels full with fluid and my nose is stuffed or leaking 3-4 days a week for almost 2 years. It is miserable. I have been to tons of drs now going to a new ENT and not getting anywhere. I am sick of it and don’t feel good taking these meds either. I can up negative to allergies too.
