I've been a bit worried because about 10 days ago, I had a fever for a couple of days right after my dad tested positive for COVID. I just assumed I might be positive too, so I quarantined myself. Now, I'm dealing with sinus issues, but most of the mucus has gone away and I've barely got any cough left. I got a chest X-ray yesterday, and I'm really concerned about whether I should be worried about pneumonia, especially since I had that brief fever and no real cough. What do you think?
