Wendy,

Welcome to NeuroTalk. You fall sounds awful Ouch.

What you are experiencing is common to concussion. You are still very early in your recovery so try to take it easy and not worry.

The concussion specialist may have more skills than your GP or not. The vestibular assessment will be good. Rather than a simple neck massage, ask the concussion specialist about a referral to someone who can properly examine your neck. Neck injuries often make concussion symptoms worse. Getting neck issues resolved will be a big help in your recovery. A physiatrist (Physical Medicine and Rehabilitation ) may be helpful.

Let us know what the concussion specialist says. Then we will have some better understanding of your situation.

In the mean time, get quiet rest and avoid stress.

Check out the thread Vitamins and supplements, It has some good links at the bottom of the post.

My best to you.
