Delay from exposure to minor rxn?
We had a possible minor reaction..actually weeks ago now and I haven't had a chance to post about it. DS is PA (6yrs old)...rxns have been immediate but no definite rxns in almost 4 yrs since diagnosis. Also Hazelnut class 1...no clue what that rxn would look like but suspect possible vomiting episode that occurred last Thanksgiving 4 hrs after eating was his 'sensitization rxn'.
I picked ds up at a playdate (well trained mom 3 houses down) and noticed him swipe at his nose. I asked him if he was OK...something only a mom would notice because it was an 'uncharacteristic gesture'. He says he's fine...didn't eat anything, didn't put anything in his mouth. No other symptoms other than a couple more swipes at the nose.
4 hours later he eats a Ballpark hotdog (open pack) on a Wonder bun (pnut/tnut free plant) and a yoplait smoothie (General Mills eaten them literally about 300 times). He starts coughing a few minutes later. Peak flow is down to 70%. He's wheezing a bit...haven't heard am audible wheeze in 4 yrs either despite numerous asthma episodes. He's got his shirt up + is scratching at his torso but there's not a mark on him. Administer albuterol...peak flow jumps back to 100% and he's perfectly fine to this day!
Now I realize I will never be able to figure this out. But there's been a lot of discussion recently on how reactions seem to happen faster and faster as time goes on. DS has always reacted to pnuts immediately even before he was anaphylactic. I am wondering if it was trace contact or trace ingestion on the playdate, is it possible the reaction would then be delayed 4 hours or is the amount of protein or mode of exposure irrelevant to timing, in your experience?
