Im 18 years old a week ago on sunday I passed out at work and went to the ER and they didnt say what caused it or anything they sent me home. On tuesday I had a doctors appointment and while I was in the office my blood pressure hit 174/118, he sent to me right back to the ER and they kept me over night and said they didnt know what it could be. Well Ive been passing out since then and it makes 10 days today ive been doing this I passed out again at work today I havent been able to breathe that well either! What could this be or causing it?
