I have asthma & allergies, and since Sept 2011 I have been having episodes where I feel like I can't breathe , very short of breathe and feeling full like. I have also been coupghing so much that I actually hear my lungs flapping sound and almost throw up. I used to be on singular and that had helped some. I had went to the ER for it in Sept and they treated me with breathing treatments that I did for almost a month it was so bad.  It seems to also be worse after I eat. I start to cough and feel the need to throw up my food almost. It seems to be getting worse. I was just treated with prednisone this past week for allergy induced asthma that was turning to bronchitis. But still hacking up a lung. I do have a full physocal schedule soon so I can address this all to my dr and get something done. What do you think may be going on with me ? Thank you.Nicole
