Scent allergies

The first time I became aware of being allergic to anything except metal (infection after ear piercing at age 7), I was in college and I accidentally got a smear of Bath'n'Bodyworks juniper-scented hand sanitizer on my face. Half a day later, my throat had swollen so nearly closed that I felt it rubbing against itself on the inside whenever I swallowed. It lasted almost a week, I think.

The next time that happened was years later, but it's become more frequent with time. Today's reaction is at least 2nd since the start of 2013, for example, but I'm pretty sure it hasn't even happened a total of 10 times in the last 12 years. The severity varies, presumably depending on how much of the allergen is involved. It's never been worse than the first time or caused any trouble breathing, but it is about equally painful to the sore throat portion of a cold, sometimes worse. It's constant for a few days and varies from slightly less irritating than a typical PMS headache to "AUGH I HATE EVERYTHING".

The only time it's happened that didn't involve a scented product actually in contact with my face, it was from drinking a lavender herbal infusion. Even though using lavender-scented soaps have never irritated me to my knowledge, lavender oil is my prime suspect for that reason. I'm aware that it is often used as an ingredient in other scented products, without necessarily being represented on the label, and it was also the second ingredient in the second-to-last product that caused an outbreak (a tea tree oil mask from the Body Shop in June).

I've also noticed my nose becoming way more sensitive to odors as I get older: not that they smell stronger, but that they're physically irritating, with like a kinda burning sensation or instant sneezing; and then I panic, fearing another one of these throat-swelling reactions. This is usually due to somebody near me, or in the elevator before me, wearing too much perfume.

Among other things, this has engendered a burning hatred of the way products everywhere are scented, both from second-hand contact and because I now prefer to buy unscented things JUST IN CASE, even though the vast majority of scented toiletries don't cause any problems, but finding unscented toiletries varies from impossible to difficult. And also it has led to me probably glaring at strangers in public who have obviously been bathing in perfume.

I know people take stuff like Claritin daily if they're allergic to dust or pollen or w/e and I know people take some other something if they're, say, allergic to cats and coming to our place for a party. But is there an OTC medication you can take *after* your allergic reaction? Because I can't see taking preventive measures for such an unpredicatable and infrequent occurrence.

mushroom and spinach pasta with parmesan

I found a recipe for creamy mushroom pasta sauce that substitutes yogurt for the typical dairy products and I've used it for a while with varying success, but lately I've been trying to cut out dairy because unfortunately I find that I feel healthier that way than eating lactose-free versions. So after I fried the mushrooms in butter with basil, then cooked them with the spinach, I added rapeseed oil and lime juice instead of yogurt, then grated a generous handful's worth of parmesan into it and tossed it. And I liked the result better than the version with yogurt! Now I feel cheated for all the times I needlessly used yogurt (frequently adding it too soon and curdling it).
