I woke up today with a weird throb in the side of my head, right above the left eye. I took two ibuprofen, and went back to bed since I have the day off. But an hour later it was still there. And now, 4 hours later, it’s still going. It’s not constant. It happens about every 10 seconds. And when it does, it not a small pulse, but a rather lengthy one. Should I be worried? Hoping caffeine solves it, but I have never really had something so odd before.
