Throbbing pain at upper parietal lobe

Hello, my name is Ann, Im 20.
About 9pm (9th april 2010) i got a throbbing pain in the upper left parietal lobe of my brain after been doing my assingment/facebooking/etc with my laptop for the whole day( from 8am-9pm). i decided to go lay down. I ended up falling asleep. This morning i woke up with pain at the same spot. It's still  progressing.
-Upper left Parietal Lobe
-Throbbing pain
-No headache, just the throbbing pain at that one spot
I would like to know if im dealing with anything serious here and if so what is wrong with me

Hi,
Migrianes can cause unilateral throbbing head pain...Mine are always unilateral and located in my frontal  temporal lobe area .I am a bit confused that you say you had no headache but you describe throbbing pain.....????

If you have never experienced anything like this before it might be a good idea to contact your doctor.
