I'm 18 yrs old.Ever since I gave birth a year ago, i've been having these terrible breathing problems.I have a cough that hasn't gone away ever since i came home from the hospital.I get to the point to where I have to gasp for air at times and the cough makes me throw up.B/c of the cough my eyes water,i get very sweaty and it feels like pressure in my chest.I feel relief for a week or two but it always comes back.When I take a deep breath,I feel rattling in my chest.The doc gave me medicine once but didnt help.When I wake up in the morning,I spend 20 minutes sneezing,and blowing my nose.The sneezing is mainly only in the morning and I've had that for a year also.What could this be?
