Hi, I'm A 19 Year Old Girl And For The

Hi, I'm a 19 year old girl and for the past few weeks I've been experiencing a throbbing sensation in my head (headache) because of a pulsating vein in my right temple. It tends to persist throughout the day but only worsen near the end of my day. Could it be something serious that I need to check out or is it a common occurrence? Thank you for your time.
