The best way to deal with the possibility of a subtle neck injury is to treat your neck as if it has a subtle neck injury. This means being disciplined about sleeping and resting posture. It would also mean no LARP as that creates too much risk for head and neck twisting. I had to be very careful cleaning up after my dogs. I had to learn to turn my shoulders to scan the yard rather than twist my neck and head.

My myo-facial release expert physical therapist could tell I had some issues and would do some gentle traction with mobilization. The muscles around the neck, especially those behind the ears tend to spasm and become tender to the touch.

If you have a head ache, try icing the back and top of your neck. I have a recipe for how to make crushable ice packs in the sticky above called Vitamins. Look at the bottom of the first post. The vitamin regimen would also be good to consider. Anti-inflammatory meds, ibuprophen, Excedrine, etc. can help.

My best to you.
