Im 24 years old,5 5 and 215 lbs. I am having chest pains from a car accident and I am getting this bubbling sensation in my chest and am having shortness of breath. I was told it sounded like I had a small hole or rip in the sack that holds my lung and it would heal within a couple days and it has been a month since the accident and i still am having this problem. I am also getting pains in my back in the area of where my lungs are when I yawn. Any answer would be helpful ...thank you!
