<s>[INST] I experience chest discomfort while exercising which also causes burping.     Pain subsides within seconds of stopping.       Not heart related as dye test did not show any blockage.     Taking id, 20mg daily for Gurde however this is not helping as i still feel pain and discomfort.     Also when walking in wind and/or cold and shortness of breath climbing stairs.Can you advise? [/INST] According to your history, it seems related to heart only,, If ur angiography has been done a way back, repeat it...& some other structural heart conditions can also do these symptoms...so get your 2D Echo done..& also it can be related to your rib cage, e.g.costochondritis...so, try pain killers before starting exercise to ruleout it...i think 2Decho will answer your question </s>
