Can anyone tell me what this is in her when we woke up she had it

It’s all over you can just see it more in those spots

did she eat anything different? Is it itchy? It's hard to say because it looks like heat rash, but also like an allergy rash.

the only think she ate different she ate pork with Chinese food yesterday that was the only thing she ate different

No they barely even itch I haven’t seen her scratch it’s just the bumps

It was an allergic reaction to the pork
