About 2 weeks ago, I became ill with an upper respiratory virus. I was running fever for a few days but had very little cough but did have wheezing. Last week, I developed a dry cough and still wheezing, especially with activities like walking, going up or down stairs, etc. This week, I still have the same cough and wheezing as well as some shortness of breath. If this was a virus, should I go to the doctor?
