<s>[INST] hi..last 4 weeks, i developed shortness of breath, and saw a doctor  and he gave me nexium last week. But both breathlessness and yawning still high. Feel chest pain some times also. Cheat xray was normal. Can you advice, what is the cause?. Also, can Hiatus Hernia be cured by chiropractor? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Chest pain with breathlessness is commonly seen in cardiac and Pulmonary causes. Cardiac causes like heart failure, coronary artery disease (CAD) etc. cause similar symptoms. Pulmonary causes like bronchitis, pneumonia etc. can also cause similar symptoms. So better to get done ECG and 2d echo to rule out cardiac diseases. Get done chest x-ray and PFT (Pulmonary Function Test) to rule out Pulmonary causes. Hiatus hernia can not be treated by chiropractic ways. For definitive treatment surgical repair is needed. Hope I have solved your query. Wish you good health. Thanks. </s>
