cmp intolerant children -- any develop an egg allergy/intolerance later?

[ilovemydogandMrObama]

DS was diagnosed as CMP allergic when he was 13 months old, and aside from soya, he hasn't developed any new allergies.

He seems to have had a reaction to something, and emailed his dietician who suggested that it could have been egg and he will need to be tested. It kind of makes sense as he had egg a few days ago and his face turned red.

Any advice?

No advice really, but when I had DS tested for milk allergy they also tested for egg and he turned out to be allergic to that too. I don't know why they tested for egg as I hadn't noticed or mentioned a reaction to it, maybe the two are commonly seen together?
