Screw the Pain Medication

Someone is hurt pretty bad, yet still conscious. They need medical help, likely need surgery. They're getting ready for a major operation, but they order the doctor not to use pain killers, let alone major anesthesia. Sure, they know they're in serious pain and need to be treated - but for these folks, whatever the reason, pain isn't much of a problem -- to the point that they may outright say, "Screw the Pain Medication!"

This trope is often used to show one of many things: the patient is a badass Made of Iron; they simply don't feel any pain; or, in some cases, pain killers are in short supply, and they want them saved for someone who really needs them. Maybe ego -- or the need to look tough for someone -- won't let them. Or maybe there are downsides to taking the meds that are worse than what the pain will entail. It's often seen when a character engages in Self-Stitching, where such medication is either rare or not present. This can go Up To Eleven if it's a Life or Limb Decision.

Fan Works

In the Real Person Fic Just Taken, Melanie strictly requests that she isn't given pain medication after she is severely injured in a fight, which included getting ran over by a car. She even woke up during the middle of emergency surgery, which she just shrugs it off. Of course, this request was later denied when she finds herself in a different hospital, whose staff administers the medication by force. Melanie complains that the medication was making her even worse, wanting to vomit at one point. However, considering one of the reasons for admission against her will was due to her eating disorder, she wasn't able to do so.
In Spice Fortress Series, none of the women are given any medicine, even during surgery, yet seem not to care.
Though understanding why she had to be on them, Emma wants the doctors to either reduce or stop giving her medication when she got out of a coma in Astral Journey: It's Complicated, as they were just making her very sick, even worse than being in a coma.

Literature

The Cardinal of the Kremlin by Tom Clancy: After getting shot, a state trooper notifies his superiors about those who shot him and their hostages. He declines to take any medication for pain.
In Saga of the Forgotten Warrior, Lok's Protectors of the Law can draw on the Heart of the Mountain to increase their strength, speed, stamina, senses, healing, and pain tolerance, but can choose how to distribute it among all those benefits (thus one using it to boost both strength and speed will be slower than if they exclusively focused on speed and weaker than if they used it to increase just their strength). On a few occasions Protectors are shown using the Heart's power exclusively to heal without using it to dull their pain to maximize the healing they receive, either to heal faster or to survive very serious injuries. Additionally, Ashok, the main character, receives a few injuries whose pain he could use the Heart's power to dull as well as heal, but since he knows the Heart's power, while vast, is ultimately finite across all users (so it will eventually run out someday) he refuses to waste its power dulling pain.

Live-Action TV

This is true of Barry Allen in the CW series The Flash. Thanks to the effect his Super Speed has on his metabolism, pain medications wouldn't work for him anyway.
In the Breaking Bad episode "One Minute", Hank beats Jesse so badly that he puts him in the hospital with a horribly bruised face, leaving the battered and broken Jesse in a state of near-feral rage.

Video Games
