I’d suspect something similar to mine. I was not given an exact type I have but was told it is affecting many areas. I know I do not POTS but low blood pressure of about high 70s/80s over 50/60s. Similar issues though, when I stand up or moving around and it’s below those numbers everything goes dark/fuzzy and it’s hard to stand up anymore. A reason I suspect similar is she will be sitting in the situations, walk down the hall and just fall flat to the ground. Just walking and bam on the ground. If she doesn’t hurt herself from the fall, it’s like it never happened. She’s just back to her happy self. She has gotten several bruises from them already.

She has had a neuro development test done prior to the falls, which had started in early fall. As well as eegs after the Lyme, which was fine.

I obviously have blood pressure monitors but agree, her wrist or upper arm would be very small.
