Heaviness Post covid. Now? what to do?

I had covid in April 29 and then got -ve in 14 of May. After that my chest started to feel heavy. To rule out Cardiac issues, I did the following tests:- ECG, ECHO, D-Dimer, BNP, TNI, MYO, CK-MB on 20th May. To rule out pulmonary causes, I did the following tests:- Chest X ray and PFT. All tests were normal. But still I feel the need to press my chest frequently and I hear crackling sound sometimes. Even in the morning when I wake up, the upper left back pains which is somewhat muscular. I have no pains in chest but have the frequent need to press it. What to do now? History:- Non alcoholic, Non smoker. Initially post recovery, I had palpitations for which I took Beta blockers for sometime. I had mild deranged ALT and AST also for which I took precautions post covid. But right now my only problem is this chest. What to do?
