My boyfriend started going through a peanut butter and honey sandwich phase, which I joined in with him this past Wednesday. Later that night I noticed one of my toes felt like it had a blister on it. Thinking nothing of it, I've had about three sandwiches in the past few days. Last night, Friday, all of my toes were swollen. I don't recognize any hives, however there are about four small white dots, flush with the skin. I can't fit my foot into any of my shoes and it feels like I'm walking on a huge blister. It doesn't itch, however if I scratch it it feels better. It hasn't spread either.

Has anyone ever heard of this? Can a food allergy cause your feet to swell? This is the only reason I can think of. Advice?
