question: Good Evening sir I am 40 male.Recently I am feeling uncomfortness in the left side of the chest. I feel littlie tightness in chest and occasional shortness of breath which will usually go off with belching. some times I feel this this pain is external to chest bones. I have regular habit of walking for 4 km which take 40 minutes. I have done ECG, 2D Echo , TMT, Lipid profile tests. All are fine. ( Total Cholesterol:161, Triglycerides:106, LDL:88, HDL:52,VLDL 21). The doctor told it may be due to acidity and prescribed antacids. Can I simply forgot about this pain. Afyer how long I have to go to tests.
