Pulled Muscle From Coughing

I have been coughing for about two weeks. I took a Zpac and coughing subsided a lot. Last Friday, I noticed a pain right under my right breast is sensitive to touch, and it hurts when I breathe deeply or cough. I took Motrin since it started and it tends to alleviate pain.

Could be muscle pain. Your productive cough that you cough up phlegm? Probably a doctor visit is in order to remove pnuemonia or bronchitis. Two weeks is a long-time cough.
