Mike, that's a hard way to go. A county or two a way from me a young lady and her fiance' were discussing their wedding arrangements while sitting on some hay bales. Suddenly they realized they were getting covered in fire ants. She died of an allergic reaction from the bites, even before she could get to the hospital. Very, very sad. Venomous insect bites for people with allergies can quickly turn into life or death situations. The bad thing is that many people don't know that they're allergic until they're stung.
Btw, just because you swell up like a balloon doesn't mean you are allergic...that is usually just a normal reaction. On the other hand, if you start getting a rash and it starts getting even a little hard to breath and/or swallow you need to be seeking out medical treatment.
A tip for the non-allergy group, multiple stings or even one sting can cause "reactions", but not "allergic reactions"...too many stings can sometimes push you "over the edge" even if you're not allergic. For the bad stings for non-allergic people, where you want to keep the swelling down and the itching to a minimum, try to keep some children's benadryl in the medicine cabinet. The reason for keeping children's formula is that it is liquid and gets into your system the quickest. When I was actively keeping bees and got into a mean hive (I don't use gloves normally) and ended up with several bee stings, when I'd get to the house I'd take a scientifically measured amount of the children's benadryl...the measuring usually consisted of turning the little bottle up and taking a good swallow.
Some people react differently to benadryl...some it makes drowsy, some it's like drinking a couple of 6-hour energy drinks. So, be aware of that. I don't know whether it could help with anaphylactic shock as a stopgap until you could get to an epi-pen or not...better for people with known allergies to keep an epi-pen handy. When I was actively keeping honey bees I kept an epi-pen in the medicine cabinet for anybody's need...just in case.
