Today Is First Day I've Ever Had Short But Sharp

Today is first day I've ever had short but sharp pains in my left temple. I only lasts about one second. It has occurred about 7 times in about 10 hours. I usually never have headaches at all, or if I do, they are very mild and only occur when I'm tired. Never this sharp though. I am a little tired today. I haven't been out in the sun or doing anything unusual.
