This is going to hurt. Which is why whatever it is (most often surgery) is preceded by painkillers of some sort. At least, most of the time. In this trope, something means the character chooses to go through the experience with no anesthesia.
This can be used to indicate that the patient is a badass, that the situation is dire, or both. Alternately, this can show that the patient Feels No Pain. (If no one knows he doesn't feel pain, he could be going for some cheap badass points.)
Another variation of this trope is when a character wishes to use an alternative to modern anesthesia. Hypnosis and acupuncture, among other methods, have been used to block pain in Real Life.
This can be Truth in Television. Modern general anesthesia both paralyzes the patient (to hold him still) and blocks pain, there are proven cases where the mix was off and only the first effect occurred. Someone performing Self-Surgery will be limited to local anesthetics at best, and in a Life-or-Limb Decision situation there may not be any painkillers available.
While to be fair, this should be limited to eras/universes where anesthesia is available in the first place, this doesn't limit us by much. The sap of the opium poppy was used by the Minoan civilization, and that's not the only herbal painkiller out there. The painkilling effects of ethanol would also have been known for at least as long.
Can happen as part of Meatgrinder Surgery, but not always.
- Gunslinger Girl. Hilshire is wounded carrying out an assassination mission he should have assigned to his cyborg Triela. When Triela discovers this, she flees in tears as she's been conditioned to protect his life at all costs. Hilshire tracks her down and they return to their hotel room, where Triela has to remove the bullet using a pocket knife and no anesthetic, because Hilshire is worried she'll try running away again. Hilshire passes out anyway from the pain and Triela does decide to walk out on him, but barely makes it out the door before having a Love Epiphany.
- In Higurashi: When They Cry, the villain's Evil Plan requires vivisecting one of the protagonists. Still, the villain is courteous enough to note that although the victim needs to be alive while their entrails are being pulled out, they don't need to be conscious for this, and offers them a general anesthetic. In the one arc where the victim remembers their previous lives in the "Groundhog Day" Loop, they refuse the anesthetic, hoping that this will burn the villain's face into their memory, so their next incarnation has more time to stop the bad guys (it doesn't really work, however).
- In the "Dingos" episode of the Black Jack manga (later adapted as episode 28 of the anime series, "Wilderness Epidemic"), Black Jack performs Self-Surgery to excise parasites and infected tissue while he's being stalked by a pack of dingoes.

- The Bourne Legacy has Aaron remove a Tracking Device in his hip once he realized he was being targeted as part of The Purge. This is done swiftly out in the Alaskan wilderness and it looked quite painful. It was later established that the "chems" Aaron and the other operatives take are designed to either delude or help them to ignore pain.
- Subverted in the film version of The Fugitive, as Kimble had to stitch up an injury sustained in the bus crash and was seen sticking in a needle before doing the procedure. It still evokes the trope in how he is performing surgery on himself.
- In Little Shop of Horrors, Orin, the sadistic dentist, only uses laughing gas for himself.
- Subverted in The Martian. Mark Watney gives himself local anesthetics, but removes the piece of his biomonitor before they take effect.

- Played for Laughs in Jerry Lewis's Cracking Up (aka Smorgasbord: The Movie). Dr. Grassnover Perks (played by Lewis), a sort of Buddhist monk, has a ruptured spleen and needs surgery. On the operating table, he tells the surgeons "No anesthetic," and explains that he will put himself into a deep trance where he will feel no pain. The doctors are incredulous, but ultimately agree. Dr. Perks invokes a silly-sounding Magical Incantation, lies back, and says "You may begin." Of course, the whole thing is subverted when, as soon as the lead surgeon makes the first cut, Perks yells "Ouch! That HURTS!!", and runs around the operating room yowling with pain.
- In the film adaptation of Master and Commander: The Far Side of the World by Universal Studios, young Lord Blakeney takes severe damage to his right arm during the first skirmish between the French ship Acheron and the British Surprise.

- In Tom Clancy's The Cardinal of the Kremlin, the state trooper who was shot refuses pain medications to stay conscious and inform his superiors about his shooters and the hostage in the backseat.
- In The Stars My Destination, after Gully and Jisbella escape from prison, they go to a Back-Alley Doctor to have his Embarrassing Tattoo bleached from his face so that he's less recognizable by the authorities. Since the two have just had a nasty argument, she puts up money for the procedure but not the anesthetic. Eventually though, she can't stand his pain and gives in and pays the extra money.
- In Ender's Shadow, the villainous Achilles is granted surgery to fix his lame leg. Achilles has a pathological need to always appear strong, so he insists that the doctor not give him anesthetic, but she refuses. So for putting him out so she could mend his leg, Achilles kills her.
- Happens in Rocket Boys when Sonny cuts his wrist open on some scrap metal and almost bleeds to death. At first he accepts the doctor's offer to give him a shot before the stitches, until he's told that his father didn't take any after being hurt in the mine. Sonny instantly changes his mind once the needle goes in and screams "Deaden it! Deaden it!" but the doctor cheerfully says that it's too late.
- Lensman: Played with in Gray Lensman. Kinnison has barely survived torture and needs radical surgery. He offers to just keep his mental nerve block up, but the doctors convince him that he needs to be out cold due to possible psychological trauma from what they'll have to do to him. Then the anesthesia only blocks the pain and leaves Kinnison conscious. Worsel has to be brought into the operating room to put Kinnison under via mental powers.
- In Derek Robinson's WW2 air epic Piece of Cake, Squadron-Leader Rex refuses anesthetic because he feels he cannot be spared from the air war over France. He does not want to be sidelined with a woozy head and unfit to fly. The medical officer then sighs and tells him to hold on tight, as he removes a lot of German shrapnel from Rex's back and buttock muscle. Far from taking time out to recover, Rex then goes back in the air having demanded a stimulant drug to keep him awake and alert.
- In Cheaper by the Dozen, Dad decides to have his tonsils out with only a local anesthetic to show the children that they're being wimps. He winds up coming home in bad shape.
- The Greater Good: When Cain is faced with cutting off his own leg to escape a Tyranid spore's grasp, Jurgen offers to get a local analgesic out of his first aid kit. Cain would love to take one, but he doesn't think he has time to spare. (He was probably right, though since the Reclaimers chose that moment to arrive on the scene it was a moot point.)
- It's hard to find in English, but there's a Gabriel García Márquez story in which this is played for drama. The mayor of a small town comes to see the town dentist with an abscessed molar. The dentist makes up a bogus reason why he can't put him under anaesthesia, but really it's to make him suffer for being part of the military junta that killed some of the townspeople.
"Now you're paying us back for those twenty dead men, Lieutenant."
- In Stargate Atlantis, when they first met Ronon he revealed he had a tracking chip at the base of his brain stem that the Wraith used to track him down for sport. As he didn't trust the others, he insisted Dr. Beckett perform fairly intense surgery with him awake, sitting up and holding his gun. Subverts the norm as he passed out from the pain once the chip was removed.
- An episode of Burn Notice had Michael with a bullet in the back from an assassin trying to kill him. It was from a ricochet and wasn't deep but still hurt like hell. As he didn't want to have to explain it to a hospital he had his brother fish it out, and the narration brings up that he had to deal with third world medicine before.
- Justified in The Flash (2014). Barry's Super Speed also increases his metabolism to the point that if he did use anasthetic it would burn right through him, making using them pointless.
- Game of Thrones, "Kissed by Fire": When Qyburn tells him there will be "pain" when he cleanses Jaime Lannister's amputated stump, Jaime simply says "I'll scream".

After Plankton swallows it, he runs back to the Chum Bucket as fast as he can and orders Karen to perform surgery on him right away to get it out of his stomach. Karen asks Plankton if she should apply anesthetic first, but Plankton tells her there isn't time for that, as they have to get the patty out before it's digested. Even with the anesthetic skip, the krabby patty is already half-digested, much to the horror of the customers who tried to order krabby patties from the Chum Bucket.
- During the Napoleonic Wars, a lot of amputations were conducted without anesthetic even though both alcohol and opium were available. Part of the reason was that it was considered unmanly.

He underwent complex dental treatment without sedation. His dentist remarked that the pain must have been excruciating, but Hitler withstood it without flinching.
- It is sometimes advisable to ask a dentist to not use anesthetic for a minor treatment, as the tooth nerves are only affected if the holes in your tooth are very deep, and the numb feeling inside your mouth is rather unpleasant. Sometimes avoiding the bit of pain you do feel even when the drill doesn't hit the nerve, is just not worth it.
