I have experienced these same BP extremes and have no answers as to why. After many work ups, the closest we’ve come to an answer is maybe some autonomic thing. Mine is more predictable whereas if I am sitting it’s high, and if I’ lie down long enough, it goes low. The medication I’m on is not enough to make it the highs come down to normal, but it’s too much to keep the floors at a safe MAP. Although our situations are not identical, they are close enough to where I understand many of the challenges you face of trying to live life that contains such extremes.
