[|Human|] Dear Doctor i have a question my little brother has problems breathing.His chest gets tight and isnt able to get the full breather then gets scared and panics.We took him to the hospital he got xrays and all the doctors say hes fine but it still happends 3 times a week to 4 and im still kind of worried.Any advice?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should first rule out asthma in your brothers' case because asthma can cause chest tightness, breathing difficulty and chest x-ray is normal in asthma. So consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test). If PFT is showing obstructive defect then asthma is more likely. If PFT is also normal then no need to worry about asthma. Sometimes anxiety and panic disorder can also cause similar symptoms. So first rule out asthma in his case. Hope I have solved your query. I will be happy to help you further. Wishing good health to your brother. Thanks.
