Can any doctors explain to me what field this is

Low self-esteem.
Study of mental illnesses
As an old and now retired medic, once again EMS gets left out. Our caudecus is twin snakes with a pair of wings attached to the rod.
Some say the snakes tell you we are real, honest to god, professionally trained medical personnel. And not just an overpriced taxi service.
The wings indicate we will fly to your medical emergency as fast as we can. Because the louder you scream, the faster we come.
And the rod is the gear shift lever that tells how fast we can shift from 'This ain't nothin' to 'Oh shit we gotta go. We gotta go NOW' And 'Inject ALL the diesel' modes.
And finally our motto: "I'm always willing to bet your life I can keep you alive long enough so you can die on some doctor and not me"

Here's some more:

I think the English version came first though
Finally someone justifies using a caudecus as a medicine symbol.
https://en.wikipedia.org/wiki/Caduceus_as_a_symbol_of_medicine
Honestly I feel like Hermes having domain over alchemy is a decent enough pretext
Single snake is Rod of Asclepius. A caduceus is 2 snakes and the staff has wings.
Yes. Im talking about the heart one cos it looks like two snakes.
actually....
I was a couple months ago old when I found out that the medical symbol they use is of 2 snakes doing it.
No.
Been more involved with orthopedics than anything else
Lol at tits and ass on the cosmetic snek.
Thank you for properly representing the Rod of Asclepius instead of the Caduceus!
Caduceus - 2 snakes on a winged sword - human medicine
Asclepius - 1 snake on a stick - veterinary medicine
No , look, the caudecus isnt a medical symbol. Someone ages ago in america got it wrong and used it everywhere and now people are confused and use a symbol of hermes god of merchants as a medica...
OMG you fools, this explains why none of you can afford healthcare
Dionysus - Snake on a stick: Yum.
Doesn't Caduceus symbolize trade and commerce?
Yes, that other comment is crap.
No.
Btw, why the snake on a stick?
It's the Rod of Asclepius, not to be confused with the caduceus!
There are various theories why this symbol was invented. The one that makes most sense to me is that it depicts a (formerly widespread) parasitic nematode being removed by wrapping it around a stick to slowly draw it out of the body.
For a visual demonstration of the parasite and its removal: Bizarre Beasts - When is extinction the 'right' choice?
There's also just the use of snakes as a symbol of rebirth and healing. I feel like people know the difference between a snake and a worm, personally
You're probably right, yeah...
It was the symbol of Hermes, the Greek god of messengers. It's called a caduceus, and it was a symbol of peace that would grant safe passage to the carrier. For similar reasons it would be adopted by medical experts and come to be associated with medicine.
No.
I deeply want someone to draw a version of this for Scientology.
I'll never go to a gastro pub again
Opthalmology looks goofy enough to be me.
Okay, I choose... that one!
I never considered that snakes have a butthole they poop from this just looks like a hole was drilled.

my first time using ML image generation lord forgive me, never again
"orthopedics"??? isn't it "traumatology"?
I will never understand this people (USA)
Europeans refusing to learn etymology again... You would think they'd have an easier time with this.
It actually makes more sense when you learn that American English is formed by the foreign languages of the people who immigrate here. But Europeans also have issues with foreigners so I guess that adds up.
No, because orthopedics covers congenital stuff like scoliosis too
Entirely different things, and I think the meme actually correctly corresponds to orthopedics. It's a pediatric specialty, and unfortunately, most of the treatments are some form or another of restraining body parts so they grow straight. Hence the snake tied to the rod in order to remain straight instead of wrapping and slithering around.
