Well, we had our consultation with the allergist today. He was very nice, took a very detailed history, and asked if I wanted the scratch test done today. I figured we might as well since we were there anyway, and they're currently booking appointments into March so it would be a while before I could get it done again. We did milk, egg yolk, egg white, peanut, dust mites (apparently a very common cause of eczema, which I didn't know) and orange.
Got a strong positive result for milk, as expected. Got a weak positive for egg white (likely the cause of our Christmas morning reaction). And finally, got a very strong positive for peanut, which was NOT expected. He's never had peanut before, but has likely been exposed to it as DH and I are not very careful with it (for example, I'll be eating peanut butter toast while feeding D breakfast - he's not eating the pb, but likely is coming into contact with it). They even redid the peanut scratch, and got another positive result, though weaker the second time. *sigh*
Now we have to go in for blood tests. Dr said that he normally doesn't like doing blood tests on children as young as D, but given that he is in a daycare setting he felt in necessary. So we're blood testing for those 3 positive results, and also for mustard, which they didn't have available for the scratch test. The only good news in this whole thing is that one of the other reasons he wanted blood tests was because children with eczema can react to scratch tests due to their sensitive skin - so he *may* not have a clinically significant allergy to the peanut or the egg, though he clearly does to the milk. Also got prescribed 2 epi pens - one for with us and one for daycare - due to the severity of his reaction Christmas morning.
I don't know what I was expecting from this appointment, but am so disappointed. I got results, but I still have to put D through more tests. He was just so upset this morning, and now I have to do it to him again next week for the blood work. Poor little monkey doesn't even understand what's going on

I know so many others have it so much worse and feel guilty for being so upset over this, but I just hate putting him through all of this. I just want him to be healthy.
Thanks for letting me cry a bit.
