This has been happening a LOT to me lately. I am wondering whats wrong!! It used to be a long time ago when I would get up out of bed sometimes i would get dizzy and my vision would blurr so I could no see for a few seconds. And then I would be perfectly fine. Now this happens to me every day about 5 times a day. Every single time I stretch, and often, but not always when I get up from my chair. What can this mean? Any ideas I dont know whether to be worried or not.
