I don't have an answer on the hema/hemo at the moment. Anyone?
My father just had the electrolyte test done. Results aren't in his hands yet but when they are i'll see a copy and know more.

I take pazosin (minipress) 2mg 5x/day for my blood psi which would skyrocket if it wasnt for that med due to what I was told 21 yrs ago after spinal cord injury is autonomic dysreflexia. My body can't control the size of my plumbing anymore for 3/4 of it since im paralyzed from chest down therefore EVERY time I have to go #1 or #2 it spikes till either passes. I sweat, oh it's so annoying. Never caused any fainting or seizure moments.

Is your high blood psi the cause or result of blackout? If it was the cause, i'd say give the med I take a shot at maybe 2x day? It does lower it a tad overall. Im usually 90/60.
