Lightheadedness, no vision, tingling sensation and vertigo- what causes this?
About 6 months ago, I got out of the car after about a 15 min drive, and as soon as I stepped out, my whole body went limp, I couldnt see anything, my whole body was completley numb and tinglng and I immediatley fell. This was the first (and thankfully) the last time I've ever experienced it this bad, but those same feelings occur quite often now, almost daily if not more, and I would like to know if this is serious, or if not, just what it is.
It not only happens when I get up after sitting, its happened while im walking, and most of the time, after sitting for very short periods.
Thank you, please help me
