Slight headache(if that?) in back top left of head?

For the past week i've had small pains in the top left back area of my head. its not really a headache but more of a pain that will throb for a few seconds then go away. it has been coming and going for a little while now and ive just been taking asprin which seems to help. it has slightly gotten worse but not a whole much. its not too bad of a pain either, nothing to moan about but im just curious if this could be something serious. i have had a panic attack a few days ago since i suffer from panic disorder and it seems everything is making me paranoid(yes i know what a pussy right? god i had f***ing panic attacks! if youve had one you know what i mean) and would just like to know if i should maybe get this checked out. could it have been the attack that caused this?
