A true allergic reaction occurs fairly quickly - from minutes to several hours from ingestion time. Reactions that occur days later are not allergic reactions - might be a food intolerance or food poisoning, or have absolutely nothing to do with food.

No, usually not. That is too long for an allergic reaction to happen from a food you've eaten. Mine usually happens (depending on how much I consume) between a half hour to an hour after, starts with a headache, then I get hives. I have, however, gotten migraines from a specific food the next day, but 3 days later is really pushing it.

Usually a sensitivity to a food will show up in 24 hours. A true allergic reaction is immediate. Throat swelling, hives, red in the face and tightness in the chest. If you have these , seek medical help now.

For me it depends upon what the food is. When I was allergic to raw fruits and vegetables, the reaction occurred in less than five minutes. For my poultry allergy, the reaction may be as long as 12 hours later.

If you have an IGE mediated or "true allergy" your symptoms will show in 15 minutes to 2 hours.
If you have an intolerance, it could take a a few days to feel the effects.
