I have tried Vicks and Asthma inhaler but its not working. I read that itd be easier if I was sitting up, but thats not helping either. I have to take short gasps of air when I try to breathe. Please help me out. Thanks - Sarah Hetherington YYYYYY  <response>: HI, thanks for using Chat Doctor You need to speak to your parents or guardians about this concern. Difficulty breathing may be related to varied causes such as: 1problems with the lungs such as asthma. Since you are a known asthmatic and having trouble breathing, an acute asthmatic attack should be considered first. You need to speak to someone and get assessed quickly2nasal obstruction due to infection, allergic rhinitis, mass in the nose, abnormal structure of the nose3any obstruction or abnormality along the upper airway-pharynx, larynx, trachea4heart disease5anxiety-this is only considered if the other conditions are ruled out hope this helps
