My boyfriend and I spent about 4 hours out on the lake today fishing, it was over cast and he got slightly burnt from not wearing suntan lotion, we just finished dinner (ate the 3 fish we caught) and all of a sudden he mentioned how stuffed up his noes is. Now his face is extremely swollen, especially his eye lids, could this be from the sun or food or both? He is not allergic to any type of food that we know of. Any help would really be appreciated!
