I'm trying to figure out what's going on with me. I had mild to moderate pneumonia from COVID last month, and I tested negative after 23 days. My CT value at that time was 7 by 25. Right now, I'm just taking Perfitab. But whenever I skip the meds, I get this really annoying burning or itching feeling in the middle of my chest, and it only seems to happen when I'm resting. I don't have a cough or any breathlessness, so I'm confused. Is this something I should be worried about? Could it be lung fibrosis or something else?
