I sit on a pillow in the car, and used to use a soft neck brace. I also take curcumin, which I noticed help maybe 10-20% (my rough guess). I found aleve to be much better for headaches than any other NSAID.

For me, my head sensitivity is in the front of my brain on both sides. I used to get a burning sensation, but now it mostly just feels like pressure. If I get a bad enough head turn, I stare and zone out really bad for a while, feeling dazed. But this has happened only twice.

To my surprise running doesn't cause symptoms if I don't overdue it, but a quick head turn can. Even the impact from showers leaves me a bit "off" for an hour or so. Thankfully, I'm well past the anxiety stage of having this, which can make a big difference.
