When it comes to allergies, other than "delayed reaction", are there other kinds?

What ?? Two weeks later !

@flo 2 hours but not 14 days later.

Basically, there’s anaphylaxis, (immediate life threatening), immediate, and delayed. I have had delayed reactions that have lasted a week to 10 days before they eventually subside to the point where I feel more or less normal again. I’m sure there’s a medical term for immediate and delayed, but I’m not going to look it up.

“Phantom reaction”?

My daughter is allergic to pork. She lives in Japan, where it’s impossible to completely avoid it. Eating pork makes her skin break out in itchy painful acne that lasts for weeks.

There are 4 kinds of allergic reactions:
Type 1. Immediate like asthma and anaphylaxis.
Type 2 and type 3 associated with blood, infections and autoimmunity and vary in time of manifestation.
Type 4. Delayed. Like dermatitis, rashes etc.
