I am not in well to do any activity because whenever I do some physical activity like walking around my home or climbing stairs and I start feeling weird chest pressure and pain in my upper body which last for hours and does not subside by rest... Due to a young age And normal reports over course of 2 years cardiologist does not suspect anything serious and he says it is likely due to my over sedentary lifestyle My last Tmt was in March 2019 and it will be two years soon.. I am living in fear that I will die from some heart disease because the symptoms exactly match like that of the Angina
