His symptoms are consistent with a diagnosis of post concussion syndrome manifesting itself as HEADACHE of the ice pick variety. The more technical term for these types of headaches would be TRIGEMINAL AUTONOMIC CEPHALGIA and following any strong blow or concussion to the head they can appear usually in the area where the blow occurred. If you would like to know more about how these headaches come about and such write me to www.bit.ly/drdariushsaghafi otherwise, even though no CT scan of the head was obtained I believe at this point your best bet is to get him baseline tested and seen by a NEUROLOGIST (one has either an interest or experience with TBI patients (traumatic brain injury). There are many other LONG TERM issues that can come about and should be watched for in terms of his school, academics, behaviors, potential development of psychiatric aberrations, etc. But first is the need for a good baseline assessment and also to make sure he is following an approved CONCUSSION PROTOCOL which virtually all public schools and colleges are following nowadays when it comes to these kinds of injuries. He needs to be taking regularly scheduled testing that will give doctors a better idea of when he is ready to go back to play than just waiting a week or 2 or asking how he feels, etc. There are more objective measurements that are looked at these days for sports related concussions.
