Dr Leddy can say your neck is not involved but that relates to your good days. You said your bad days are right after a work-out or physical effort. My neck is fine except when I sleep on it wrong. Then, I have nightmares and a bad day. But, nobody has been able to find anything wrong with my neck.

The common PCS neck injury is very subtle and only causes problems when specific circumstances happen.

My solution was to figure out my own therapy or change in behavior. I had to learn to not look side to side with my neck only. I had to turn my shoulders too. This was very important when I was scanning the backyard looking for my dogs' waste.

My neck is much more stable now that it was but it creaks like an old wooden floor.
