<s>[INST] I just experienced sharp chest pain as I headed up steps. I stopped and decided to lay down. Had some cool green tea that tasted funny, metallic. I had no breathing trouble but I did take a few deep breaths. Fine after 20 minutes. 59 years old, morbidly obese, type 2 with a 7 A1c, low cholesterol. Mild afib. [/INST] Thanks for your question on Chat Doctor. In my opinion, we should first rule out heart related diseases for your chest pain. You are having many risk factors for heart diseases like obesity, diabetes, age more than 55, chest pain on exertion, fibrillation etc. So likelihood of heart diseases is high in your case. So get done ECG, 2d echo and stress test (trade mill test) for the diagnosis of cardiac disease. Lose weight. Strict control of diabetes is needed. If all these reports are normal than no need to worry about heart diseases. You might be having muscular pain only. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
