Sharp pain in left side of head near temple lasts for 30 seconds happens 2 or 3 times a day happened for a week now?

This area. you are "describing" sounds like it may be your temporal ARTERY and inflammation of that artery may be connected with some important medical conditions! JUST BECAUSE OF THE LOCATION , I suggest a HANDS ON examination by your PCP (Primary Care Provider) Hope this is helpful
