It does appear that he may be having a possible allergic reaction or hypersensitivity. Monitor to make sure the swelling doesn't increase and that he has no trouble breathing or swallowing. If it doesn't get worse it is likely self limiting and should resolve over a day or two. If it worsens definitely contact your veterinarian.
