I keep on getting sharp pains in my head. I got them yesterday and I took 4 advil and they only went away when I fell asleep. Now they've return and the pain feels worse than before. Yesterday the pain was just in the center of my head , but today the pain's around the right side of my head right above my ear. So far I've take 4 advil and it still hasn't went away. Is it serious and do I need to go the the doctor, or is it nothing to worry about?
