Yesterday me and my older brother were standing in line for food outside and it was really hot, I started sweating and the grass started looking hot green and my vision started getting darker. I tried closing my eyes so it can go away but it didn’t, the sky was purple and everything else was black. It happened two times that day I couldn’t see well. It was really scary

I have it almost Everytime when I stand up. It's not something new. It's getting annoying. I often faint almost and even sometimes I actually faint. When it happens my legs don't have any strength anymore but when I try to stand it hurts also my back. It's getting annoying always sitting back down and never standing up directly.

Ronny Don (2 months ago)
I don’t just get dizzy, I can’t see, my vision is filled with tv static for a few seconds and I don’t have any medication (except for my inhaler but I don’t realy take that ) and I get one every morning, and it happens a bit after I stand up, or when I’m walking. My friend said it’s probably just migraines, but I don’t really think so, cause it’s tv static not little dots

Hailey (2 months ago)
I stand up a lot and my vision goes black a few times a day but I never passed out but yesterday I hadn't eaten or drank enough water so when I stood up it went black I waited for it to clear up but next thing I know is I'm on the ground and super confused. Lol my friend said I was screaming but I don't remember doing that?🤔
