Chest pain which comes and goes. Help!

Hi, I have recovered from covid 19. It's been 43 days from the date of tested positive. I never faced any difficulties after recovery. During covid I didn't ised any steroids. From past 4 days I am having chest pain which comes and goes. I am using pantop 40mg morning and evening but there is no use. And also I am having heart palpitations during sleep, this makes me unable to sleep. Yesterday I went for cardiac checkup and doctor told me that there is no problem with the heart and he prescribed me some antacid tablets and syrup. But I am still having that mild pain in chest and heart palpitations at night. I am attaching all the reports which came out normal according to the doctor. Lipid profile is normal. I need a second opinion on this. Please help!
