Mark,
He had headaches but he seemed to have them all the time at first and they were different than a typical headache, he described them as pressure and sometimes tingling or tearing at the top of his scalp. He took Ibuprofen for headaches and it is unclear as to whether this is the best drug but it worked for him and gradually he needed less and less. He had difficulty sleeping and took Melatonin for over 6 months, 2 tabs and then weaning down to 1. Both of these drugs were acceptable with the concussion specialist we were seeing at the time. He was dizzy most of the time and this seem to bother him the most. When he was really ill with symptoms he just withdrew down to our basement and watched T.V for weeks at a time. He was in a "fog" as he described it and hated detailed questions about how he was feeling. He probably was in a depression but his youth(17) and optimism that his mother would solve this for him may have kept the depression down. It is a very tricky domino affect. You will get better and you need to remain positive and keep your anxiety level down. I would say he had anxiety issues more than depression and he would periodically get easily overwhelmed. He is now happy, motivated, doing well in school and heavily exercising. All issues faded away. Reinjury is our only worry and he is not live wrestling anymore for his high school team. This caused more of a depression for awhile but he is adjusting. Take care of yourself, time will heal.
