What Causes Severe Headaches,flank Pain And Lethargy After A Fall?

Hey, I'm sixteen and I am a cheerleader. I fell from a stunt about 10ft in the air. It's been a year ago this month. My symtoms are getting worse. I have splitng headaches and there mostly on the side I landed on(right) but sometimes on the oppsite side(left). I get dizzy at random times. I feel tired all the time no matter how much sleep I get at night. I wake up every few hours during the night all night until I have to get up for school. My appetite changes all the time. I also have horrible mood swings. None of my doctors know what's going on. Do you have any idea?
