So from past few weeks, i sometimes feel i am getting short of breath once in a day, which happens for a min or so with rapid pulse and then goes away. I have chest tightness also that is mostly feel while taking a deep breath..but no cough and fever. I got my chest xray. Please advise if it is fine and if i am facing some panic attacks. In between i also faced gerd issues, food stuck in throat and chest feeling... ecg is normal. This is making me very anxious and hypochondriac.
