I don't think the shock would do that- most fence zapping is startling but not damaging. It probably wouldn't take a few days to show up either. I would guess it is completely unrelated, swollen face means it is probably time to have the vet out, could be an abscessed tooth or jaw fracture, or even an allergic reaction. Best of luck!
