I'm really in need of some advice on this annoying chest pain I've been experiencing. I had covid back in January with a really bad cough and something called "covid tongue." My HRCT scan looked normal, and I was treated with Fabiflu. But a week after I started feeling better, I began getting this dull chest pain mostly around my sternum. I got an X-ray, which mentioned increased bronchovascular prominence, and a PFT showed COPD in the restrictive area with moderate obstruction. My doctor put me on Foracort 200 and some muscle relaxants, which helped, but the pain still bugs me at night, sometimes radiating to my mid-back. I've had two normal ECGs and another CT scan recently, which showed nothing unusual in my lungs. It's been four months, and I'm still waking up with this chest pain. What's going on with me, and how much longer might this take to get better?
