Pain after injury
The vast majority of facial fractures happen after a trauma- car wreck, assault, fall.
You should have sought emergency care; thry should have examined with hands and maybe ct scan
to look for these. If it's far after the event, you may notice that the teeth don't fit together normally, there are changes in the coutours/rough edges when touching the face, there's pain or the eye
(s) may sink in.
