->''...and I got all the symptoms, count 'em 1, 2, 3.''
-->-- '''Music/BonJovi''', "[[LoveIsADrug Bad Medicine]]"

SequentialSymptomSyndrome is a gag in which one character (usually a doctor, but not always) describes the effects of a disease or a poison while someone else (usually another character who happens to be close by) experiences those same symptoms in exactly the sequence the first character is describing. If reciting symptoms ''causes'' a person to experience them, it might be InducedHypochondria.

Usually PlayedForLaughs. When it's not, it can get very close to being Nightmare Fuel.

SideEffectsInclude and the FiveStagesOfGrief are often handled in a similar manner. Often a DiagnosisFromDrBadass.

[[folder: Anime And Manga ]]

* In ''Anime/FullMetalPanicFumoffu'' Sousuke describes the effects of the trap he set as it shows the coach who set them off with the symptoms.

[[/folder]]

[[folder: Comic Books ]]

* This happens in ''{{Cerebus}}''. In this case, the main character was [[InducedHypochondria conning someone into believing they had a plague]], so the symptoms were largely psychosomatic.
* In a recent story from ''{{Cattivik}}'' our anti-hero spends the whole story suffering the infernal and disgusting symptoms of a virus as soon as the medic on television mentions them. He eventually tries to stop them by swallowing a whole truck of medicines, but it backfires horribly as the virus had exhausted his life cycle anyway.

[[folder: Film ]]

* In ''Film/{{Airplane}}'', Rumack describes the effects of the food poisoning in exhaustive detail, while the camera lingers on Oveur in the foreground, the poisoning's latest victim. He goes through each and every symptom in turn as Rumack describes it, the poor bastard collapsing when he is reduced to a quivering wasted piece of jelly.
* The new ''Film/StarTrek'' film saw [[TheMcCoy Dr McCoy]] gives [[TheKirk Kirk]] a vaccine against viral infection from Levaran Mud Fleas in order to fake a medical emergency. He then treated the symptoms in sequence as they occurred.
-->'''Kirk: ''' Whass... whas hahpenun wi' my mouf?
-->'''[=McCoy=]''': You've got numb tongue.
-->'''Kirk''': ''Num tum??''
-->'''[=McCoy=]''': I can fix that!
* A rather violent version of this trope occurs in the Creator/JetLi film ''Film/KissOfTheDragon''. Li's character uses Kung-Fu acupuncture to make a guy's head explode. Li describes the physical symptoms as the man stands paralyzed.
-->''... you will begin to bleed from your eyes...''
%%* Happens in ''CarryOn Matron''.

[[folder: Literature ]]

* In ''Literature/{{Dune}}'', Feyde-Rautha is well known for describing the effects of the poisons he uses in the arena, though not on screen.
* MatthewReilly uses this to introduce is fictional bio-weapon in ''Area 7''. It mostly results in liquification of internal organs.
** [[BodyHorror Internal organs]] ''[[{{Squick}} in sequence]]''.
* In Assassin's Apprentice, part of the ''Literature/{{Realm of the Elderlings}}'' collection, Prince Rurisk is poisoned whilst talking about poison. When the poison takes effect, Fitz and Kettricken believe he is pretending to be poisoned in order to emphasise his point.

[[folder: Live Action TV ]]

* In the third ''Series/{{Blackadder}}'' series episode "Nob and Nobility", the Scarlet Pimpernel [[PoisonedChaliceSwitcheroo unknowingly takes a suicide pill intended for someone else]] and explains the symptoms induced by it, oblivious to the fact that he's exhibiting each of them as he describes them.
* One of the few surviving fragments of ''Broaden Your Mind'' (a precursor of ''Series/TheGoodies'') has Graeme Garden's character (presenting a programme) listing symptoms, while Tim Brooke-Taylor's character (watching it) experiences them.
** Up to and including "[[http://www.youtube.com/watch?v=zgjtewM_c9w ...and the standing lamp falls on your head.]]"
* ''Series/StarTrekTheNextGeneration'' - "Realm of Fear": Barclay has the computer read the symptoms of "transporter psychosis" and acts out the symptoms as he hears them. Somewhat justified as the character is a hypochondriac, though he actually ''has'' been suffering some of the symptoms described (such as excessive thirst and tingling in the extremities) but not some of the others. After the computer readout, he constantly tries to examine himself for the symptoms he ''hasn't'' yet suffered (such as vision problems). [[spoiler:It turns out his problems are ''not'' transporter psychosis, but a different phenomenon that nonetheless did happen during transit in the transporter.]]
* In one episode of ''Series/{{House}}'', House uses this to prove that the sick passengers on a plane who were thought to be suffering from a deadly outbreak of meningitis (which started when one passenger exhibited real symptoms of a meningitis-like illness) in fact are simply under the effects of mass hysteria and psychosomatic illness. He announces that the original sick passenger did indeed have meningitis and that they may be infected if they have any of a long list of symptoms, including the nonexistent symptom "trembling in the left hand." Cue a planeful of suddenly shaking hands.
* Joanna experiences this on ''GreenWing'' when Harriet rattles off a list of symptoms of ''pregnancy''.
* In ''TheNanny'' episode "Ode to Barbara Joan", Fran was explaining how kids deal with disappointment:
-->'''Fran:''' They're not going to tell their father when they're dying inside. They give off signals. They act morose.\\
''(C.C. is moping outside)''\\
Sometimes they even have fits of anger.\\
''(She smashes a pot)''\\
And, finally, if they're despondent enough, they might even be driven to acts of violence.\\
''(She stomps in Niles's foot, which had been causing him agony from corns)''\\
[[LampshadeHanging And that concludes today's audio/visual demonstration]].
* A non-disease-related example. There's a song performed on ''HelloCheeky'' which kicks off with "''How'd ya like to squirt me with a soda seltzer, baby? How'd ya like to hit me with a pie?''" and gets gradually messier from there. It's performed twice -- the first time, it's just the song. The second time, the singer is attacked with what he sings about after every verse.
* In the ''{{Community}}'' episode "Epidemiology", the group hides from the zombie partygoers in the study room. Rich, the doctor, tries to hide the fact that [[ZombieInfectee he's been bitten]] and details the symptoms of the contagion. He's already displaying some of the symptoms he mentions, then adds one last one: slurred speech...with slurred speech.

[[folder: Theatre ]]

* In ''The Changeling'', a tragedy by Thomas Middleton, a drug used to test virginity causes certain symptoms, which are first seen in a serving maid and then faked by her mistress for the latter's fiance.
* ''Theatre/BullshotCrummond''. After a PoisonedChaliceSwitcheroo, Bullshot lists the effects of the [[SlippingAMickey knockout drug]] he's slipped into Count Otto von Bruno's drink.
-->'''Bullshot:''' You want to curse me von Bruno you can curse me now, for I have slipped you a deuced large Mickey Finn. You will shortly feel the effects. To begin with a crippling pain in your stomach. Followed by slurred speeshhhh ''([[NonSequiturThud breaks off into incoherence and keels over unconscious]])''

* A non-medical example: In "[[http://www.youtube.com/watch?v=QcXiUSZPuWA Muppet Labs Experiment 5T832: Ghost Hunt]]", Dr Bunsen Honeydew lists possible signs of paranormal activity, while behind him Beaker encounters each one.
* Occurs in the Waverly Films short [[http://www.youtube.com/watch?v=Mi4FpNz_Moc The Infected]]

[[folder: Western Animation ]]

* In ''WesternAnimation/TheSimpsons'' -- the episode where Homer eats fugu and thinks he's going to die -- Homer experiences the five stages of grief as quickly as Doctor Hibbert can recite them.
* In {{Disney}}'s ''Disney/TheSwordInTheStone'' Merlin describes the effects of malignalitaloptereosis to Madame Mim, who experiences this first-hand.
* Characters/BugsBunny, describing the effects of Rabbititis in ''Hare Tonic Hare''.
** Bugs does it twice in that episode- first to Elmer Fudd, then to the audience.
* In one episode of ''WesternAnimation/TheMask'' the common cold turns out to be the only thing that can kill the Mask. The symptoms are actually numbered from one to seven, and serve as a sort of countdown [[DoomyDoomsOfDoom to doom]].
* ''{{Chowder}}'' experiences the effects of eating a raw Puckerberry as Mung lists them.
* ''TheBoondocks'' - The Fried Chicken Flu episode has Huey explaining to Jasmine the symptoms of the eponymous disease while Tom suffers the effects of salmonella poisoning, having eaten tainted Buffalo Wings.
* On ''WesternAnimation/RocketPower'', Reggie and Otto get the "Fiji flu" from Sam. The doctor describes a few of the symptoms being a high-pitched voice and irritability. As expected, they undergo both.
* After trying to hide it for several decades, Prof. Hubert Farnsworth finally confesses to his employees in the ''{{Futurama}}'' episode "The Tip of the Zoidberg" that he long ago contracted an illness known as Tritonian Hypermalaria. Amy reveals that she recognizes the disease as "the one that causes fever, insanity, spasms, coma and death", with Farnsworth acting out each symptom as it's said (save for death, which instead a {{Beat}} followed by "Yes, you moron!")
* Happens to Helga in an episode of ''HeyArnold''. She looks up the symptoms of monkeynucleosis, a long-debunked disease, and is relieved when she finds out she only has the first symptom. Then, when the book slips from her hands, she realizes she has the second symptom, sweaty palms, and starts to notice the others showing up in sequence. Of course, since the disease isn't real, all of the new symptoms she notices are purely psychosomatic.
* The "Ice Station Impossible!" episode of ''WesternAnimation/TheVentureBrothers'' features the Goliath Serum, and drug that turn the recipient into a living bomb. As Brock and the boys watch a filmstrip describing the serum, Hank obliviously displays the Stage 1 and 2 symptoms.

[[/folder]]

[[folder: Real Life ]]

* Happens and inverted with people known as hypochondriacs. On one hand, they do give themselves symptoms when someone tells them about a disease. On the other hand, sometimes they will do the opposite, they'll have genuine symptoms of something, but they're usually generic (the typical headache, nausea, fever, etc.) Rather than assume something benign, such as a cold, they tend to automatically assume it's a rare fatal disease and they only have months to live.
