My headaches would get even worse, if that was possible, from talking, walking, slight noises...any kind of movement and my head felt like it was going to explode if the car hit a bump!!

I too was a runner and that always helped with anxiety so after the concussion I could not run and that made me even more anxious, I remember the PT telling me people who were very active before a concussion quite often relapse and healing goes South as they try to do too much (I learned that the hard way

I would go for extremely short walks and that was months after the concussion, accident was over a year ago and now I can walk further but have to watch it.

Ice helps!

Hope you get some relief soon.
