question: I have had a cold, mainly a cough since November. It was a cold, went away and came right back. I am not sure the cough ever really stopped. Now I have pain in the right side and back when I cough. I have no fever (I did during the main part of the cold) and my energy level is okay -not great but not terrible. I have to sleep sitting up even with Nyquil. Is there really anything I need to be concerned with?
