<s>[INST] I am 57 years had triple vessel graft 2 years ago and on full medical treatment . I still have chest pain at rest and when taking deep breath plus feeling of sob which last one to two hours when i walk there is burning sensatin after 10 min which diappear after 4to5 min rest what should I do now thanks [/INST] Thanks for your question on Chat Doctor. I can understand your situation and problem. Since you had cardiac surgery in the past, we should first rule out cardiac cause for your symptoms. Your symptoms like intermittent chest pain, shortness of breath etc. are commonly seen in heart diseases. So first get done ECG, 2d echo and if needed coronary Angiography to rule out heart diseases. If all these are normal than get done chest x-ray and PFT (Pulmonary Function Test) to rule out bronchitis. As bronchitis can also cause similar symptoms. So you should consult doctor and discuss all these. First diagnose yourself and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
