I've taken care of thousands of "spider bites" and not one of these people ever saw a spider bite them.
Next time you have one of your epic "spider bite" patients, ask the patient what the spider looked like.
Ask them, "What makes you think a SPIDER bit you?". Almost always, the answer will be, "well, mah aunt Junie's half-brother-cousin is a mekanic, ya know, so that makes him an expert in SPIDA BITES and he looked at it and says it is and he's NEVER wrong and spiders love my blood, I'm like spider man I have spider blood ya know!"
"No sir, you are not special. You don't have spider blood. This was not a brush with death nor a brush with the most and fatal elusive creature on earth, that you will survive only because of your inner warrior. In fact, your skin is teaming with a vile, all too common germ. You have a common abscess. Actually, that makes it sound much too special for you to be able brag about for the next 47 years long after your chain smoking Jack-drinking, couch sitting lifestyle allows you to long outlive me with my tea totaling, marathon running, parasite hosting lifestyle:
You have nothing more than a big infected foul smelling puss filed zit. If I do nothing, in two days, it will pop, drain and heal up on its own over a couple of weeks. But since you're such a douche-troll, and since your lack of a meaningful employment means you are likely to fill out your Press Ganey survey, I will do a field block, slap a bunch of powerful brown spider bite killing medicine on it, slash it open with a silver plated scalpel, give you the most powerful combination of medicine in the solar system called bactrimkeflex, write you a script for pain medicine fit for a king (plus a sample pack to go), a cab voucher, Sierra mist and meal tray while you wait, sit down while I talk to you and introduce myself to everyone in the room with you including your common-law wife, 7 sons with the same first name, grandma, great grandma, and great great grandma. AND in two days, it will spit out its last brand of ever so common puss, and heal up in couple of weeks just like if I had done nothing.
Thank you sir,
Please come again."
