Beelezbore,

Did your WorkComp case get terminated ? You should reapply for WC care.

Your neck needs gentle care. There are no cartilaginous disks in that location. The joint can get injured and end up with an osteo-arthritis like inflammation. Icing it may help. A PT or chiro who knows how to do gentle upper cervical treatment would be helpful. It is also very important for you to be disciplined about head and neck posture during rest and sleep. A straight posture is best. Minimal elevation from a pillow. An expert with prolotherapy may help.

It take weeks and months of discipline to help this joint heal.

If your head hit the concrete skateboarding, no amount of rolling out of your fall will lessen the impact. An impact is a few milliseconds of force.

No more skateboarding. Maybe some day you can return with a helmet. Helmets don't prevent concussion but can reduce the severity by a very small amount.
