I wanted to chime in. I'm around 8 months post-concussion. I have sensitivity, but I've noticed some improvement in the past month or two. I used to be very sensitive to any kind of jostling--for the first few months merely shaking my head would reproduce this sensitivity. Going over speed bumps in a car would do it for a while, or merely taking "hard" steps, such as down the stairs. These activities do not now produce as much sensitivity. I am hoping that eventually this will go away, but this whole process is so pain-stakingly slow that I am not optimistic.
