This is something new to me. A doctor discusses the dangerous period of day 8-11 with covid for having dangerous blood clots. The whole thing is interesting but long. If you just want to hear about the clotting issue and how to resolve it, go to minute 22-24 and watch for a few minutes. Then you can decide if the rest is worth listening to. This is a doctor that has had lots of experience treating covid patients.
