I have a severe tree nut allergy, and I tried the challenge approach in the allergist's office. After 5 hours I ingested one whole almond, but because I did not show any symptoms in the office he told me I could eat almonds (ha, ha). I didn't have a reaction until 2 hours later. My tongue began swelling. Needless to say, I stay away from all tree nuts!
Thank you for your response. I am beginning to believe that my issue is autoimmune. If I eat too much wheat in any given day hours after I eat it my throat begins to swell (scary stuff). It begins with my tongue and goes directly to my throat. I've been to a number of allergists and their response is, " keep doing what you are doing." I am taking Claritan every day and using my EpiPens when necessary.
I have reactions when allergens reach my lower intestine and end when I pass the offender. Alkaseltzer GOLD (NOT BLUE) or baking soda in water or in capsules with water, ease and generally eliminate my reactions if I catch them early enough--meaning as soon as my tongue starts to tingle or my throat gets tight or chest starts to wheeze or I start to itch....IF I catch if immediately, I can avoid further treatment unless it's to my previously nearly fatal reactions requiring 3 weeks in the hospital--then these baking soda based products keep me from dying before I can find the EpiPen in my bag. I AM NOT SUGGESTING YOU STOP USING YOUR PRESCRIBED TREATMENTS! Simply ask your doctor if it might be a first step aid to relief. It's used intravenously in hospitals to help your body recover--just as activated charcoal is in drug overdoses to adsorb (correct spelling) the drugs and help pass them safely from the body.
Sadly I cant do the same. As a kid and teen my Mom tried the exposure method and it didn't help. My allergic reactions only got worse, so i avoid them at all costs.
I can relate. My reactions take longer the more time goes on, so I have no idea if the food I eat was safe or not. But as time between reactions gets shorter I can definitely identify. Though its been a while.* Knocks on wood* I have been extremely careful
