Hi i fell on my head on tuesday i went to do doctors got cereblex and teplan i did head skull e-ray all okay but now since saturday my one eye bigger?

Head injury: I don't know what teplan is and I assume the other medication was celebrex, an anti-inflammatory medication. If one pupil has become enlarged or if you have severe headache,nausea, confused feelings,visual disturbance, dizziness, you should be examined in the emergency room where a head CT scan can be promptly done to check for intracranial bleeding and brain injury.
