During our exit interview with the neuropsychologist (the one who sabotaged me with a bought and paid for report) he asked my wife about a deep wrinkle in my forehead, which my wife said was new since the concussion. He talked a bit about it, said it was a muscular tension issue that should be addressed because it could be contributing to the headaches, or symptomatic of them or something.

Of course this didn't end up in his report, that was just a WC hit piece, but I felt like when we were talking with him after the evaluation he was genuinely pointing out some things that were helpful. Has anybody heard about this? Was he making it up, and what the hell for if he was? There is a deep wrinkle, almost like a slash in my forehead since the concussion (not from a contusion or anything, I wasn't hit there) and most of my pain is either in the forehead or top of head.

I agree that it could be a sign of muscle tension that could lead to head aches. The important issue in my opinion would be to find the source of the muscle tension. Is it a skeletal issue or is it psychological? Either way, I don't think it should impact WC as a concussion can cause both symptoms.

Sometime, you can palpate the muscles to find a sort of road map to an underlying problem.

There also may be some relaxation exercises that can help.

Worth some effort, either way.

My wife sometimes notices stress and strain in/on my face. They usually accompany head discomfort.

Hope you find a solution.

My best to you.
