Dysautonomia/orthostatic intolerance is when the BP drops upon standing, not rises. Your BP IS supposed to rise upon standing (to some degree) to keep blood in the brain even when gravity is trying to pull it down.

They should have done an MRI to rule out stroke for this last incident (which sounds like tell-tale stroke symptoms). What test did they do when you presented to the ER with those symptoms?

I'd be interesting in seeing the link you are referencing that says dysautonomia cause BP rising with standing...I have never heard that before and have had dysautonomia for 19 years (my BP drops upon standing and that is the classic presentation).

Your BP sounds fine...but your other symptoms are VERY concerning for stroke/TIA and should be followed up.
