There is nothing the neuro can do to speed up your recovery. You are in charge of your recovery. Your discipline to get quiet rest and avoid stressors is the best you can do.

The CT and MRI are of no value and can even have a negative value (radiation) and supporting a legal argument that you are malingering (faking).

You need a good mTBI/concussion attorney to protect your need to support and care for your wife.

The one thing that may help would be finding a doctor or Physical Therapist who has good diagnostic and treatment skills for whiplash. Whiplash often makes a concussion much worse. The upper neck injuries from whiplash can be very difficult to diagnose with images but the symptoms are usually a good indicator. Look for soreness, tingling, numbness and tenderness behind the ears and at the back of the head and possible radiculopathy to your extremities. A physiatrist (Physical and Rehabilitation Medicine) may be a good find.

My best to you.
