So what's the deal with the head rushes I get? I didn't really notice that I got them a lot till about last week, but I did have them often before. Now it's really often and pretty bad. Basically every time I stand up, I get a head rush, I get dizzy, my head hurts, my vision clouds up and I can't see anything. I have to look down and put a hand to my head and just try not to stumble/fall down and wait for it to pass.
Why does this happen to me?
Is there anything I can do about it?
