Welcome to NeuroTalk.

It sounds like you have been sensitized to concussion issues and symptoms since your concussion last October.

You need to start by understanding that tenderness on the exterior of the skull, the skin and nerves, has no bearing on the intensity of a concussion. Many get surface bumps without any concussive impacts.

It appears you have been checking for symptoms, many of which can be triggered by a concussion, sub-concussive impact, bump, or anxiety. Checking for symptoms will almost always indicate some sort of symptoms.

For example. I rarely have PCS headaches any more. But, If I am commenting to a NT post about headaches and check to see if I have a headache, I will usually sense some level of headache. If I ignore it, it just goes away.

I don't think the glance of the barbell was anything but a startle.

Avoid getting caught in the anxiety trap of checking for symptoms. You will lose every time.
