My 7 year old son has been suffering with PCS since May 2012. He took a bad fall playing hockey but didn't show any signs of a concussion. He started complaining of mild headaches a week later but then the flu bug went thru the house so we ignored the headache. About 4 weeks after the hockey fall he got hit in the jaw at baseball practice. Again, he showed no signs. Three days after getting hit he was in bed with horrible headaches and he was walking funny. We took him in and found out he had a concussion. He has been struggling with headaches in the back of his head, slight dizziness, personality and mood changes. His headaches get worse when he tries to read or think too hard so he is not doing any academics right now. We have been seeing a chiropractor multiple times per week. He just started having some craniosacral therapy done. The woman who is doing the therapy said that his neck has classic signs of whiplash. She thinks this is what is causing the headaches in the back of the head. My son is taking high does of fish oil and B vitamins. Can you please recommend anything else I should be looking into for him.

Thanks in advance for your help!
