I am a 19 year old female and most of the time when I stand up everything is very blurry or feels like I can t see anything for a couple of seconds and I feel dizzy but it all goes away within 3-10 seconds. Also lately my hands have been feeling numb and then I get really dizzy but same thing it goes away within 10-30 seconds. Any thoughts would be great!
