What Causes Dull Headache?

a few days ago i got really emotional and threw a temper tantrum. crying and yelling the works. after that episode i had a headache which is not unusual for crying and such i slept it off but my head is still hurting only on the right side. it's more of a dull achy pain that seems to float from the back to the front side of the right side of my head. should i be concerned??? or am i just over reacting? i am in college and i spend alot of time studying on the computer i have been trying to avoid the laptop but that is how my school operates. the eye strain could be the cause of this. my grand mother and cousin on my father's side both had brain aneurysms sadly my grand mother did not live and died very young in her sleep. do you know what could be causing this? sleeping seems to help it feel better but when i wake up it hurts again it's been about 3 or 4 days...
