I'm feeling really concerned because I had COVID over 8 months ago, and it was pretty severe with CORAD 5 and pneumonia. Since then, I just haven't felt like myself. I have this ongoing pain in my chest, mostly on the left side, and now my eyesight seems to be getting blurry too. I did an ECG and echo back in October, and they looked fine, and I had a chest X-ray in December and another ECG in January, which were also normal. I'm really at a loss about what to do next. Which type of doctor should I see, and is there a chance I'll ever feel like I did before COVID without all these issues?
