Fainted at school

Samantha

I fainted yesterday at school, got super sweaty, had blurry vision and then fell down from what others told me after I woke up. I don’t remember falling down. But luckily I had ppl there that really helped me. So far tests have came out negative and vitals were fine 30 minutes after and 3hrs later at the doctor. Has anyone ever fainted? Can you all give me your experience and was anything wrong or came back positive at the doctors?
