OK, just looking for a catchy title.

So I am still trying to determine what to just chalk up as 'normal' now and what is unusual. Off and on for a few years, I get a feeling on the upper-back-left side of my head. It isn't a headache. It is just a sensation, and I can't determine if it is my scalp or something else. If I touch my scalp, the sensation goes away. It isn't always the same spot, but always in that region. Anyone else with the same?

Thanks for listening. This is all a bit confusing still.
