Unemployed Chicken, I agree totally with jhm47. I'm an EMT too and in addition have had trouble with allergies and anaphylaxis (have used epi on myself). Your body is way too reactive to the sting. The next time you get stung it may be minor ... or it may be like the last time ... or it may be your life. You need to carry an epi pen and you should also make sure you have liquid Benadryl on hand (it works faster than the chewable tablets, which in turn are faster than the capsules). Your doctor can advise you on the dose but we would typically give 50 mg to an adult (in my neck of the woods that's 4 teaspoons). The Benadryl will stop the reaction but it takes 15-20 minutes to kick in. The epi will put a nearly immediate stop to the reaction but it will start wearing off in 15-20 minutes. So the epi is the immediate life-saver for someone who is having trouble breathing, low blood pressure, losing consciousness etc. If I were you, I'd be hitting the Benadryl as soon as I got stung and I'd be ready with the epi if needed. (Oh and I suspect that the YJ probably didn't kill your hen; not saying it's not possible but just not so likely.)
