Problem with my eye? Imaginary bruise?

So, this morning, I woke up feeling like somebody punched me in the eye. Now, I looked; there were no bruises or cuts, and the pain got lesser throughout the day. The only thing that kept happening is that it hurts to blink. Now, I checked for a stye under and around my eye, but there was no reason for one to appear. The pain feels like it's coming off of the bone below the eye, and it's only an inch long (area of pain when touched). Does anyone know what happened? D:
