Hi, Im a 16 year old female. Four days ago i feel perfectly normal and healthy. Then threee days ago, while i was in school during the assembly under the sun i didnt something i never before. I fainted. I dont believe its due to the heat because i am very used it to for the pass 4 years in school. I felt perfectly normal and the next minute i got a painful headache and things started blurry and next thing i knew, im on the floor. When i woke up, i cant really remember anything. I got a very bad migraine (something ive never had before). I has some water and half and hour later i felt fine. During recess i got some food and when i started walking again, i got back this really really painful headache and feels like im floating. The headaches never really went away until today. If i stand too long, i feel like im gonna faint again. WHATS WRONG WITH ME? PLEASE HELP.
