I've been sick for nearly a week now and I just been having dry coughs and sometimes I'd have wet coughs (GROSS). All of a sudden just now about 5 minutes ago I've noiiced some pain under my right chest. I was thinking that one of my lung airways has inflammation from all the coughing I've been doing. What do you think it could be? I've never had this pain before, it is totally new to me. Does it sound serious? I put some ICY HOT patch on the spot. Doesn't seem to be helping much. I hope its not a really huge problem. I don't have medical insurance because my parents never thought I needed it. I'm 20 years old, I did some situps earlier today and my abs were cramping because I did too many. Just in case some information would help. I seem to cough the most at night time and not as much in the day time. HELP PLEASE!!
