what could be the cause?
So for the past month I've had headaches that come around from time to time and goes away. Its like a sharp piercing pain not on the temples but closer to the center of my head. What could be the cause of this? I usually just take advil to make it go away but the next day it would always come back. Its getting really annoying and Im wondering if anyone knows a way to get rid of it for good. Thanks.
