For quite awhile now, I've had this problem where (generally everyday, especially in the morning, but sporadically throughout the day) when I shake my head quickly (to get my hair to move to a certain part of my head), I feel a deep, moderately severe pain. Several times though, this pain has evolved into a full throbbing sensation toward the front of my head or near my left hand ear even if I don't shake my head.
Any ideas what this is? I don't have a history of headaches or migraines, but my mother has them very very often.
