I had to get a pulmonary function test because I had pneumonia but I could not complete a single test because the therapist kept saying I kept closing my throat on every exhale. To sum up, I feel like most times when I breathe I catch my breath as if there’s tightness in my chest or my throat is closing. It seems to be an anxiety thing but I don’t know what to do about it. It’s involuntary for my throat to close like that I can’t control it. Anyone have experience?
