Throbbing in different parts of head.
Since Wednesday i have been experiencing not painful but little throbs in different parts of my head. I had just come out of a meeting with a boss at work and went out for a cigarette. Then i saw someone who i recognised and instantly my hair on my head shot up in panic as he always asks for cigarettes i dont know the person but always end up bumping into him and panic although he isnt violent i get anxious easily. Since then i had a throb in my right temple, the next day it moved to the back of my head and now its just above my ear what has caused this and should i worry?
