I'm COVID positive, but my chest X-ray is normal, and my CRP and D-dimer levels are really low. My blood tests, liver function tests, and vitamin levels are normal too, and I don't have diabetes, fever, or body aches. My oxygen levels are above 96 most of the time. It's been almost 14 days since I tested positive. Im really puzzled because I still feel like I can't breathe properly through my nose, almost like the air isn't getting in. It feels like I'm breathing rapidly and shallowly. I do have sinusitis, a deviated nasal septum, and nasal polyps, but I've had those for 3 years and theyve been inactive with no symptoms until now. Could these be causing problems now because of COVID? I'm feeling really down and dont know which doctor I should consult about this. Any advice?
