Welcome to NeuroTalk.

Yes, your neck could be a big part of your problems. If the chiro did a twist the head and pop the neck adjustment, that may have been far too aggressive. The C-0 to C-3 injury common to concussions needs very gentle treatment.

Good straight head and neck sleep posture is important. A chin to the chest position is not good.

Some gentle traction and mobilization of the cervical vertebra can help. Trigger point or myofacial release therapy or other therapy to release the neck muscle spasms is important

Unfortunately, you have discovered the limits of bike helmets. Few fit well or protect the forehead because they slide back too easily. They need to be fitted so the front cannot be pushed up. This means a chin strap adjusted to hold the helmet on the forehead.

Just curious, Is there a meaning to your screen name? It is very difficult to remember names that appear to be almost random, especially if one has memory deficits from a brain injury.
