I am currently getting over a cold, and it seems now I just have a dry cough (rarely with mucus, even then only a little) to deal with along with some blockage in my nose. However as I was moving dancing earlier, I felt a hollow feelin in my chest. It sounded like someone was wheezing, which was weird because it sounded like that even when I would hold my breath. It was like air was coming out by itself? I m not really sure how to describe it, something similar to a light airy feeling? Could there be something wrong, or could my cold progressed into something else?
