Is it a sunburn or seafood allergy?

I vacationed this past week in Florida, and unfortunately, got a sunburn. Well fast forward to like one night later and I woke up and could barely see because my eyes and face were swollen, badly! That night we had eated seafood I had crab dip. So idk if my swelling is sunburn or seafood! HELP PLZ! CUZ I LOVE SEAFOOD!
