Hi! I am a 21 year old female! Mother of 1 and 6weeks pregnant with my 2nd! For the past 3 months or so I have had this tightness in my chest and throat! Its horrible! There is NO pain, just the uncomfortable feeling that I aint getting enough air! I went to the doctor a few weeks back, bloods were normal, ecg normal, oxygen was 98%! And lungs and chest sounded clear through stethascope!had 2 ECGS,2 oxygen tests, I am a constant worrier,always thinking I'm dying when in reality I'm probably not! Does any1 else have this problem and know how to ease the feeling?doctor says its anxiety but I just don't believe him! Plz help!
