Septoplasty and turbinoplasty 9 weeks ago - my left nostril alternates closing. When I sit down or lie down, the left side closes too. I continue the Neilmed sinus rinse and my doctor has prescribed a Nasal Steroid Spray: Dymista. It helps sometimes, but not all the time. My question is: When one nostril is closed, I feel irritated and depressed...basically I feel mentally limited. Is this normal? Please help.
