From the information provided about the, "head bumps," it's hard to say whether these are concussive impacts or not. I would say probably not. The brain really is quite tough, and you don't seem to have an extensive concussive history. Just try to be a bit cautious and continue living your life.

But regardless if they are or not, I would recommend getting treatment for your anxiety. I had to. You would be surprised at the array of symptoms that anxiety can cause, including headaches.
