Well ok here I go. I am a 19 year old girl with some serious lung problems. However, I dont know what they are exactly. I go to the doctor but never get to the bottom of the problem. My symptoms in my chest are like this: I have shortness of breath, chronic chest pain on my front, sides, and back. Its almost like I feel like im drowning sometimes, fluid in my lungs. I also get the sensation that I just got the wind knocked out of me. Plus I get serious cramping in or around my lungs alot, but im not a smoker. I have a slight cough, palpaltations, rapid heart rate..All quite frequently. So does anyone have these same symptoms, or at least know what it could be? Please let me know cuz im freaking out.
