Odd Allergy Symptoms

We ended up taking our little guy to see the pediatrician over the weekend just to rule out any medical concerns that I wouldn't know about...I don't like acting opposite the recommendations of the medical professionals, even when I doubt them strongly at times.

We were fortunate to get to see the pediatrician he has seen every visit since birth.  She knows his history and her first question to me was "What is new in his diet?"  It was such a relief.  She completely agreed with my assessment of the situation and did not think a scratch test was needed at all.  She didn't specifically state that she thought it was the chicory root, but she did agree in avoiding the new milk and rather than trying new milks when his is not in stock at the store, he's okay not having it for a day or two.

We went home reassured and relieved.  His rash took about a week to completely clear up, but it did.  She also suggested mixing his Aquaphor and a hydrocortisone cream rather than using Benadryl and worrying about the potential over dose.  It worked wonders in relieving his itch and we only used the Benadryl tablet for naps and bedtimes.

Then this past week, we went out to eat and even though he had a gluten free meal, something must have been cross contaminated because he reacted badly to it.  Tummy pain, gas, not eating and just drinking, and the strangest one of all was a low body temperature.  He has had all of these symptoms before.  His low temperature never goes low enough to reach the concerning levels posted on the internet, but it makes him cold and uncomfortable.  It only happens when he's had wheat.  And only lasts as long as it takes to get out of his system (usually 3-4 days, starting around the second day of a reaction).

I researched it in my free time for two days, not finding anything that fit his situation.  Then I searched under the FPIES (Food Protein Induced Entercolitis Syndrome).  There it was.  Allergic reactions and low body temperature in the same paragraph and connected legitimately by other parent testimonies and by medical professionals.  It's only listed as an unusual reported symptom, but it is listed as happening in severe reactions.  I was hoping to find some more scientific information about why it happens and what is going on internally.  At least it is documented that it is in relation to an allergic reaction to food proteins.  I hope that I remember, but I want to bring it up at his 18 month well visit to see what his pediatrician says.
