Could an allergic reaction to a food cause one's feet and ankles swell with fluid to twice their size?

The only thing different I've eaten different today is have some enchiladas with green tomatillo salsa and after eating I noticed my feet and ankles swell to twice their size with fluid. We also had a Mexican buffet with a lot of products (taco seasoning, chili powder, salsa, etc.) that had a high salt content. Could that be the cause or something worse?
