I just watched this video and agree that it is very well-done. It was interesting because the doctors in the video spoke about the calcium channelopathy theory (as if they had proof unless I misunderstood them?) and also spoke about the connection to mast cell activation. I get so confused re: my diagnosis b/c I match so much of what they described in the video, including that 10-minute lean test and POTS. I wish there was a team like that in the US with their particular research focus and I'd love to talk to them further!
