[|Human|] I am a 21 year old male dont drink or smoke.for the past month I have had a really heavy chest and have trouble breathing like I cant get a full breath sometimes I cant yawn as I cant get a full breath sometimes my back aches and I have a slight cough
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Chest tightness, Heaviness with breathing difficulty in young patient (21 years) should always be evaluated for asthma. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).PFT will not only diagnose asthma, but it will also tell you about severity of the disease and treatment is based on severity only. You will mostly improve with inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone).Don't worry, you will be alright with all these. First diagnose and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
