So I'm a seventeen year old girl. I have been sick for two weeks with a sinus infection/sore throat, no coughing. It hasn't been bad at all, very mild. Well I was sitting in a restaurant under no physical strain at all when i get the worst pain EVER along a line of my left long along my left side almost. After the initial pain I felt kind of dizzy and like i couldn't get enough oxygen in my lungs. I could not deeply inhale without my chest hurting. I came home and the pain left but i still could not breathe good. The next morning I got up and went to the doctor, still not being able to breathe good. They tested me for swine-flu, strep, and ran some X-rays. They blamed the chest pain on the sinus infection and a little chest congestion even though they said my lungs sounded and looked clear. I had no chest pain that day(yesterday). I went home and began to breathe better. Well today I have been able to breathe fine but the chest pain is back(really bad) mostly under my left breast.
My problem is they didn't give me a good explanation for the chest pain and I'm kind of worried. I'm probably going to the polmonologist in a few days but you do have any idea what it could be?
I'm not pregnant, don't have asthma, to pre-existing medical conditions. I have never had this problem with a sinus infection before.2 AnswersRespiratory Diseases1 decade ago
