I don't think there was ever a doctor's appointment. In the original video where she brought up the concern that she might have a blood clot (the vlog with the Xmas parade), she told us she had already made an appointment.
Days later in another vlog, she informed us that she had just made an apt through her health portal.
The night before the apt was the "long talk" with Becky and she trotted out the upcoming apt as an excuse as to why she was sooo anxious (probably trying to make Becky look like a dick for ditching her to go out for pizza). She also took the opportunity to say fans were scaring her and that she didn't have the symptoms of a blood clot (even though she's the one who brought up the blood clot talk in the first place.)
She's complained of leg pain for years, ffs she's 550+ lbs. It probably does hurt but I find it interesting that her leg pain reached a fever pitch right when Eric was getting tons of attention for his neutering.
If she was as anxious as she claimed, there's no way Becky wouldn't have made time in her busy schedule to take her. In the meantime she's been soaking up all the concern, attention and asspats from worried fans on SM, giving one only a brief answer that her leg was "ok" and dodging the rest instead of just saying that nothing has changed.
My guess: she never made that apt and this is yet another passive-aggressive attempt to make herself the victim and to make Becky look like an uncaring asshole. And we won't hear another peep about her doctor or that leg again.
