Yes, See a therapist to help you learn to stop these trains of thought.

Honestly, some people get caught up with these thoughts of "Oh, I hit the pillow to hard. That must be a concussion." and their lives start to unravel in fear of every little head movement or bump.

Headaches are very easy to cause by the power of suggestion. I can get headache from reading a post about headaches. If I ignore it and move on, it goes away.

So, If you find yourself getting stuck in these "Was that a concussion?" thoughts, help to change that thought pattern would be worthwhile. It is called CBT, Cognitive Behavior Therapy. You learn to overcome negative thoughts with replacement thoughts.

Some can do this on there own by using rational and logical responses.

"Was that a concussion?" ....... " No, I landed on a pillow. There was not enough force involved. That moment of dizziness was just because I moved too fast and my inner ear could not keep up. I'll be fine."

So, stop over thinking these events and rethink them if you need to.

My best to you.
