First, Find a new neurologist. Concussion symptoms can be delayed by a week or more. The brain struggles to go on with the injured brain cells, etc but eventually, it may give up and let those brain cells die. This is when the concussion symptoms can rear their ugly head.

There are also many triggers that can cause symptoms to manifest a week or longer after a concussion. Just about any stressful event or effort can cause symptoms to manifest.

Now, you need quiet rest. Read the sticky at the top under Vitamins. It has most all the start up toward recovery issues addressed.

You may need your upper neck evaluated. Upper cervical injuries can cause a myriad of concussion symptoms. To start, try to use good head and neck posture when sleeping or resting. Sleeping with a minimal pillow so your neck is straight is good. I curl my pillow so it holds my head from rolling to the side. If you must sleep on your side, make sure your pillow holds your head up. Ice your upper neck frequently.

This should be a good start for you.
