I have been calling this Concussion Anxiety Syndrome for years. It ruins lives. The movie Concussion was a big part of starting this epidemic.

As Bud said long ago, It helps to consider if the head bump would have caused such a reaction prior to the recent main event concussion.

I talk about a concussion needing 60 to 80 Gs to be a mild concussion. That is like dropping a 16 pound bowling ball a foot onto your head.

A car can not cause more than 1 G in a hard stop on dry pavement.

CBT and other thought and exposure/desensitization therapies can help.

When CAS causes people to abandon all logical thinking, professional help is needed.

btw, I stop answering "Was this bump a concussion?" questions over 2 years ago. Answering NO never changed the illogical thinking.
