Is it possible to show external symptoms with a food allergy?

The research I've done only mentions irritation of the throat and mouth, wheezing, etc. But is it possible to develop hives and itching on your back, arms, legs, but not have any irritation in your throat, mouth, etc, when you're affected by a food allergy, such as soy?
Also, is it possibly a food allergy if the hives take a long time to go away, maybe a day or two?

I ate sushi one night, before I got to the truck, I had a hot, red, rash on my arms. It took 2 days for them to go away. In the meantime, I took benadryl faithfully...

Yes, it is possible. This exact same thing happens to me when I eat avacado products.

My skin welps up, turns red, and itches like nothing else...

I hope that this helps and good luck with your allergies!

Yes it is but this ould also be something that you touched


id suggest allergy testing and food testing

good luck

A common skin reaction is "Dermatitis Herpetiformis (DH) is an important associated disorder or complication of celiac disease which is manifested in the form of a skin rash." DH is very common and can be diagnosed by a dermatologist or a doc familiar with Celiac Disease. For more info, see these links.

Yes, you can have hives externally from food allergies.

Yes, it is possible to develop hives or itchiness that lead to an eczema condition. The rash or itchiness can take more than 2 days to go away especially if your immune system is inflammed.
