I believe I have an upper respiratory infection.. the one with the drawn out, long, hard cough :( I do feel mucous now, after a week, but also noticed a couple mins of wheezing with it earlier. It has not come in several hours since then, but someone said wheezing is a symptom of pneumonia. I don't have any other symptoms of pneumonia though, like fever, sweats, or chills. Is it possible an upper respiratory infection can have wheezing sometimes too and it is NOT pneumonia?
