[|Human|] Hi,I had an acute MI 4 years ago.  I also had graves disease.  2 years ago I began experiencing chest pain triggered only when walking.  Ruling out cardiac issues I tried antacids but they failed to help.  The pain is so uncomfortable I hardly excercise any more and have gained wait. I am now 170 lbs.  My healthy weight was 145 when I was extremely athletic.Ive become extremely gassy.  Food and water cause gas, but do not cause chest pain.  When I get chest pain walking it is usually followed by burping.  Pain will discontinue upon rest and burp.Had upper GI done last week and small hiatal hernia found with no reflux demonstrated. No one knows what is causing this gas, why it causes severe chest pain only when walking or what I can do to prevent it.  Help please is greatly apreciated.
[|AI|]  Hi welcome to the Chat Doctor You are having history of myocardial infarction before 4 year You are having pain during walking.  During activities oxygen demand increased and if infarction or angina like disease present then it can't adapt to increase oxygen requirement and hence pain. Rule out cardiac issues by blood pressure measurement and 2D echocardiography. For gas problem rule out chronic constipation, eating too fast, excess soft Chat Doctor. . Your cholesterol values, Tread mill checking, sugar measurement also should be done regularly as having MI history Hope your concern solved Consult physician for examination and discuss all these
