I really don't know what to do, and it's worrying me. For around five days I've had short periods of pain (maybe 1-3 seconds), located above the right eye, and recently mostly in the back right of the head, a bit above where the neck begins. I've also had it on the left side, above the eye as well as in the back, but at the moment it's mostly on the right side.
It doesn't get worse throughout the day, but remains constant. It doesn't wake me up at night.
