Thanks for writing to H.C.M. for your query.
I have gone through your query regarding feeling of some ressure behind the eyes even 14 hours had been passed after injury to face. Though you are not having any signs and symptoms of head injury
like nausea, vomiting, vertigo or altered conciousness.
It does not appears to be dangerous and will responce to anti inflammatory , As it looks like due to traumatic swelling. But on the safe side you may go for C.T.scan of paranasal sinuses
to rule out any fracture
in the nearby area of nasal bridge.
