First off. There is nothing normal about skateboarding. It is a risky sport. One can feel normal without skateboarding.

A hard tailbone landing can cause quite a shock wave up the spinal column. Vertical concussions can be miserable. The C-1 to occiput joint can get injured. Icing can be helpful. Whiplash can be part of the injury.

But, you response sounds like it is mostly anxiety. A minor injury can end up with an 80% anxiety and 20% physiological injury or even more anxiety.

So, if you want to feel normal, stop the risky activities and find the help you need for your anxiety. You need to remember, you have suffered previous concussions so activities that may be a minor risk to others are a serious risk to you.

Stats show that 4 to 10% of skateboard injuries are head injuries. This does not consider the concussions that are never treated.

Were you wearing a helmet ?
