So I'm A 19 Year Old Female I Weigh About

So I'm a 19 year old female I weigh about 120-125 I'm 5/5 (I felt like that should all be included) I've been having this odd feeling in my left temple like a pulse but it's big almost like a muscle spasm but idk what it is the other day I had really bad headaches but today it was just my temple being weird I've had a CT scan a couple months back and I'm assuming it was normal because no one ever called me so lol what should I do ? What do y'all think it could be?
