headaches

okay! so i'm a cheerleader & i recently got hit in the back of the head at practice & i sat down after it happened & had a major headache & pain in the front of my head. a was not dizzy so they didn't think i had a concussion. it's been 4 days later, & im still having head pain/aches at random times. my eyes have been bothering me as well. i'm not sure what could be the problem but was thinking about getting a concussion test tomorrow. what do you think this is?
