Cant fully take a deep breath.
Hi I'm Ernesto, I am a 16 year old high school sophomore. I've been having difficulty taking a deep breath I can breath normally just sometime I can't take a deep breath it gets me annoyed and its been to the point where it gets me scared. I also have symptoms like my body feels weak and stomach hurts, I have also been burping everytime I drink something even water I've had this for over 3 weeks and 2 days ago my middle back started hurting everytime I tried to take a deep breath. I went to my school clinic and my oxygen levels were normal and my chest sounded normal. I had a little cold when it begin but all that did was a runny nose. Sometimes I have to yawn to take a deep breath I haven't told my parents because I don't know if this is serious or not I bought some mucinex for chest congestion and nose congestion but they didn't work plz help its affecting my studies and job I don't know if I should have this checked out or not plz help.
