When I stand up quickly after lying down or sitting for a long time, everything goes black. Black spots seem to slowly pop out and "invade", meaning it doesn't happen all of a sudden. I also suddenly become dizzy and need to hold on to something. Is this a symptom of anemia?
Also, is it true that if you pull down the skin near the bottom of your eye and check the flesh, you can determine if a person is anemic. If the flesh is really light pink, then the person is said to be anemic. Myth or fact?
