HI, I've been dealing with daily shortness of breath for 8 months now and no one can figure it out. It's worse when I sit down, especially driving. they have done blood tests, ekg, xrays, ct scan, and ultrasound. Everything has came back normal. My gynecologist suggested trying another doctor because he believes it is something they are missing. I smoke only a few cigarettes a day, but for the last 15years with no coughing or wheezing. I had two doctors say my lungs look and sound good surprisingly. I'm a 28 year old female who has had 2 C-sections. The second c section I had very bad preeclampsia and they had to preform the c section 4 weeks early. During that procedure my gynecologist said I had unexpected scar tissue on my ribs and a lot of it. When I went back to talk to him about my shortness of breath possible being from the surgery he got very defensive and said that is highly unlikely. He also said I did not have bad scar tissue according to his medical records because it was 4 years ago. I don't know what to do or where to turn anymore. It's a struggle to breath any and every time I sit down. Sometimes with sharp chest pains. Any suggestion or or insight would be great. Especially on what type of doctor I should see who would have the best possible solution or answer to this problem. Thank you
