When I breathe deeply, my lungs feel itchy , like they can t expand fully enough, but I don t cough. I m not sick and I don t have asthma to the best of my knowledge, at least no one ever diagnosed me with it. It borderline feels like I am ready to cough but I never do. I am not congested. I get the same thing when I eat ice cream, my lungs close up and feel tight and I want to cough. What is that from? That itchy sensation is annoying. I have a pulse ox for my dad and took a reading, says 97 so that s okay.
