My throat and nasal passage swells shut I also have mucous that is like glue that falls over my windpipe. If I don't get it out my blood oxygen saturation drops. It is really scary for me and the ones around me. I had a trachea about 5 years ago. It has come back. They treat me with steroids . I want the problem fixed not masked. They are wanting to put a trachea back in because they don't know what to do. Hope someone can help.
