Like many guys of my generation, I'm not big on running to a doctor for the least little thing. Being a Canuck, I never gave much thought to venomous insects.
The other side of 10 years ago, a friend of mine got bit by something while cleaning up his garage at home (in Canada). Stop for Nothing, Work 18 hours/day kind of guy, he didn't think much of it. The catch-up dinner we had a few months later came too close to never happening; he almost didn't make it.
I don't know the medical term for it, but when he described what he saw coming out of his arm when he finally came-to in the hospital, I said "Sounds like a fuel-rail". A gear-head too, he did laugh at that dinner....... but it doesn't get more real than having a metal beam with multiple ports on it sticking out of your body, because they are pumping that much stuff into you to keep you alive.
Strong guy, no known allergies.... taught me how easily any of us can be taken down. Any unusual reaction needs proper medical attention FAST.
