I believe the symptoms that you have noted could easily be stress after
having a headache for a extended time. I would also guess he has had
other issues without telling you.
I also know that the topamax and gabapentin should help with the headache
and some of the other issues. I don't know for sure about all the other medications.
I would look for a pain medicine doctor first to make sure that he has a
good one. I would then also get a good neurologist to keep a eye on
these type of issues. It sounds a lot like these kind of things also.
But it could just be issues from the concussion.
