I doubt they checked the neck completely. As I said, a CT Scan or MRI will not identify the subtle injury to C-1 and C-2 that is common to a concussion. A way to tell if he needs treatment for an upper neck injury can be simple. Does he have tenderness to touch behind his ears ? If so, the muscles are spasming, likely due to an upper neck injury. A study revealed that 85% of concussions include an upper neck injury that is often undiagnosed.

Sometimes, a simple Range of Motion test can point to a neck issue. Can he turn his head to each side the same amount ? A Physical Therapist can do this ROM test with precision.

In the mean time, Mike should be very disciplined to sleep and rest with his head and neck in a straight posture position. No thick pillows lifting his head. No sleeping on his side with his head hanging to the side.

Unfortunately, in SC, you have to stay with the WC doctor assigned to you.

My best to you both.
