You know, I don't know a thing about his bp. Isn't that odd.
He has borderline high cholesterol (which is odd since he is the most physically fit person I personally know--my BIL was joking the other day saying he wants to train H for the Tour de France so he can kick Lance's booty...sorry Dave I know that is blasphemous to you!:)
Anyway, I have low bp also and know the feeling you are talking about. I believe that his is a little different. It is not permanent, of course, but it lasts a few days and doesn't go away with a change of position. (though sitting or laying is much better than standing)
He went to an ENT specialist a few years back when it first occurred and ended up with a diagnosis of "vertigo". No real treatment (from my understanding there isn't any unless it is a chronic condition). Frankly I was astounded that he went to the doctor in the first place.
We'll see. Right now, it is just a nuisance for him (and for me, LOL).
Now, Mojo my wise one, here is another question for you:
Why are two year olds SOOOOOOOOOOOOOOOOOOOO BAD????????
