Driving a nail into my head

[finkema]

I rarely get traditional headaches, but every now and again I get a sensation that it feels like a sharp pain in my head, almost as if someone is tapping a nail into my head. Its not as severe as it sounds, but the point I'm making is that the pain is sharp and in one specific point. It also feels as if there is some sensitivity if I touch my head in the area of the pain. These episodes can occur 6 months apart and last for a day or 2. The pain is intermittent during the episodes. I take advil, but usually never does much. I have been keeping a diary for the last 5 years and haven't found any common variable other then it occurs in the same quadrant of my head( the back right portion,the pain is never below the ear). Any feedback on what this could be or what to do is helpful. If it matters, I'm a 41 year old active male.

How long does each pain last...is it many attacks of a second or two or is it more long-lasting?
Are there any other symptoms associated with the pain?

Are you on any meds on a regular basis?

Each pain lasts for a second. I'm currently taking Simvastatin for cholesterol, but thats something I started taking this past year and I've had the pain before the medication
