So I was in class and I was extremely bored. I then decided to check what the time was on the clock so I turned my head there, but as I did, I felt a very hard pain on my head, it was very sudden. like my nerves collided or squeezed. And It really hurt..... It was fine after a about 3 seconds though but still, this isnt the first time this happened to me. I would like to know what it is and how I can prevent it.
