I’m 21 year old male, last week I have done a 2d echo as a general health checkup after I got cavity on may 2021 in the report given it says mild tr/pah and rest of the report is normal. I also have ptsd and generalized anxiety disorder which I got after covid. I have been also playing badminton for 2 months and only in the past week I started running some times I am not feeling anything during the run but sometimes I feel like chest tightness and I will get anxious and after sometime it will go away. I also gave gastric which sometimes the I feel like the gas is causing chest tightness. I don’t understand what is happening and I am feeling anxious what should I do. I have checked my lungs for asthma and the report came negative for asthma and I have done ecg which is normal and tmt test which is normal.
