Orthostatic Hypotension?

I have been lightheaded on and off for over a month now.

Apparently I am experiencing orthostatic hypotension.

I have always had low blood pressure, but this is a new one for me.  And no, I am not pregnant.

With an almost-3-year-old that I am with every day all day, this lightheadedness to the point of nausea does not work in my daily life.  

That's all I can say about this for now.  Hopefully, this is all I will say about this!
