I'm a bit concerned and curious about something. After having COVID a month ago, all my symptoms have gone away, and my SpO2 levels have been normal for a while. My chest X-ray came back normal too, which is reassuring, but I'm wondering if its still possible for there to be any fibrosis that wouldnt show up yet? Or does a normal X-ray mean everything's clear? Im just trying to understand what a normal X-ray really tells me at this point. I'm 34 and havent had any other symptoms.
