zant,

That bump was not a concussion. You also didn't 'busted open my middle meningeal artery.' You'd be dead or in a coma if you did.

That bump may have contused some layers of skin and traumatized the very sensitive nerves in the skin. This is common and has nothing to do with an injury to your brain.

Don't waste your money and such on a visit to the neuro. Instead, seek out a therapist who can help you learn to manage your anxiety.

And, Stop reading about concussions. Don't do any research about concussions. It just makes your anxiety worse.
