I passed out yesterday and went to the hospital got check out and everything was good now i have a bad headache is that normal ?

Maybe: When someone passes out but seems OK afterwards it is rarely dangerous. A headache before you passed out can be a sign of bleeding but that would be very unlikely in a 16 year old. A headache AFTER passing out could be from a head injury. Did you have the headache when you were seen? Did they address it? A CT might be reasonable. If you don't feel normal you should get checked again.
