Not a medical professional -disclaimer. Sounds like you have Empty Nose Syndrome (ENS) caused by turbinates being cut off. Go to Facebook Empty Nose Forum. My son has this nightmare condition. The dry, crusting, painful nasal mucosa, lack of sleep, and suffocation are all what he has, plus sore throat and cough from air not being warmed and conditions. Panic attacks from lack of oxygen (yet oxygen tests always register fine). Sorry this has happened to you. We are in San Diego. May help to find others who live near you.
