This could be asthma or allergies with asthma-like symptoms. I have allergies and have trouble taking deep breaths because of them. Go to your doctor and have him or her listen to your breathing. Do you wheeze? How long has his been going on for? Do you smoke? I use Advair daily to help with my shallow breathing and Albuterol if I really can't breathe.
get checked for asthma!
