It’s hard to say. Reports on his medical condition, at least the national stuff we get here in DC have been super limited.
It’s worrisome that they keep says “clots” plural, rather than clot singular. My hope would be that he had one large clot in the leg that broke apart and threw emboli to other areas rather than multiple spontaneous clots. That could be caused by any number of things. Or just be bad luck. Multiple clots implies some sort of inherited condition or malignancy, both of which would require ongoing treatment at least with blood thinners. Or anabolic steroid use. Which makes the “he looks smaller” comments interesting.
