It seems to be heat related - he does not tolerate changes in temps at all. He is the kid that is bright red when most people find it comfortable outside. He was outside both days, prior to coming in to eat (about 1-2pm). We have had the a/c on for a few weeks now.
Our pollen counts are dropping to almost nothing after cresting into the thousands, but it's been down for almost a week.
We went through this two years ago with him constantly hiving up after having been in the pool and coming in. After a few trips to the ER because it scared the you know what out of me and consulting with allergist - it was blamed on temp related urticaria. Then we dealt with lip swelling that I thought might be allergy related but again, temp related urticaria.
The bird class today was canceled - taught by Audobon, no bird food or peanuts allowed because we are dealing with multiple food allergies within the group.
He was the one that consumed most of the bread loaf prior to Saturday (seedless rye). He has never had issues with wheat, rye, barley. I do note behavioural issues with dyes and sugar. Both DH and I test negative on Celiac bloodwork (we were concerned that my other son might have Celiac on top of the ltfa).
Allergist is closed - will call again tomorrow because wild speculating sucks.
