So, I'm pretty sure I have non-allergic asthma given I can never muster enough IgE for Xolair and also kept getting negative allergy tests. Most of my triggers I would consider non-allergic - weather-related, smoke, scents and sprays, viruses etc - things which tend to act directly on the airway rather than being mediated by an allergic reaction.
However, I've just found I have a new trigger - mango, and it seems to act more like a food allergy. I had a tiny lick of a mango fruit pot thing (wasn't mine, my friend was eating it and I was curious) and boom! instant asthma reaction. It was all asthma too - no hives, swelling or anything like that. Not fun but got it under control with lots of ventolin in the end.
This is also what happens when I encounter rose, lavender, violet and some other flowery/fruity things in pretty much any form - smell it or eat it, it will give me asthma pretty quickly and with very small amounts (one time: sip of cocktail with one ingredient containing a bit of rosewater - I hadn't known till I reacted and we looked it up).
I am curious to see if anyone else has this, especially with non-allergic asthma? It seems more like an allergic trigger to me especially with things I eat, but then if I catch a whiff of rose etc in handcream or whatever it will have the same effect, and that acts more like me getting in the way of perfume or aerosols which is not considered to be an allergic reaction (see above re effect on airways).
Just to add to the confusion, I also have hayfever - apparently this is possible with non-allergic asthma, I looked it up though my consultant finds it odd. Definitely hayfever though and I need my fexofenadine and Avamys spray - I tried stopping the other day and my nose objected after a few days of no Avamys! I suspect the allergy tests weren't telling the whole story as my nose is reacting to something even if my lower airways aren't!
Anyone else? I am currently rather fed up with being a freak and having the ongoing 'trigger roulette' thing, though there are much worse allergies I know as these aren't that common.
