Trouble Breathing - Shortness of Breath - COVID

I have active covid right now. I think I caught it from our local medical megamonstergomplex. Went in Friday for blood lab, went to urgent care to get my little toenail clipped back as I ripped it half off, and had to get an ultrasound for my liver which is something new. Sunday I was sick. Wed I spent 7 hours in ER. There, at some point they did a chest xray and cat, and dagnosed "some new and some old" blood clots on my lungs. They put me on a fairly expensive medication, and I have follow up next Friday. This was not caused by covid, as "some are not new."
