There is no way anyone here on the board can advise whether you've had internal or external damage to the scope with the information provided.
Did you "square" the shot group? That means shooting a group, moving the adjustments down, say 25 clicks, move them right or left an equal number of clicks, go up the same number, then right or left (opposite of what you did previously) and see if you still shoot in the same POI?
Did you look into the scope from the objective end to see if you can see anything broken internally?
Do the adjustments move easily, or do they bind?
If you're not sure if you can determine the scope's integrity, best to send it back to Nikon with a note honestly explaining what happened and ask them to check it out. Not sure about Nikon - Leupold has a "no fault" warranty where they repair any damage free of charge, no matter if you're the original owner or not.
