"The Little Green God of Agony" is a short story by Stephen King. It was originally published in 2011 as part of the anthology A Book of Horrors.

Plot summary 

The story takes place in the Vermont home of Andrew Newsome - the world's sixth richest man - who has been bedridden in chronic pain since a plane crash two years prior. Newsome is attended by a private nurse, Kat MacDonald, who privately believes that Newsome is too cowardly to undergo the necessary pain to rehabilitate himself but says nothing as she is being paid a handsome salary. Newsome receives a visit from Reverend Rideout, who claims that his pain is caused by a "demon god". Rideout offers to expel the demon god - a process that will place his life at risk - in return for a fee of $750,000, which he intends to use to rebuild his church in Titusville, Arkansas which has burned down.

After Newsome accepts Rideout's offer, a frustrated Kat accuses Newsome of being lazy and Rideout of being a fraud. Newsome initially fires her, but Rideout persuades him to allow her to watch the expulsion of the demon god, suggesting that Kat has become complacent to the suffering of her patients due to never having experienced severe pain herself. Rideout gives Kat a broom and Newsome's assistant Jensen a canister of pepper spray, instructing them to stun the creature and capture it in a specimen jar. The expulsion is also witnessed by Melissa (Newsome's housekeeper) and Tonya (Newsome's cook).

Rideout begins the expulsion, and a small, spikey, "bladderlike" green creature (which Kat likens to a Koosh ball) is expelled from Newsome, whose pain immediately ends. The strain of carrying out the exorcism gives Rideout a fatal heart attack. As the creature emerges from Newsome's mouth, a power cut throws the room into darkness before a backup generator activates; Jensen accidentally pepper sprays his own eyes, while Kat misses the creature with the broom. The creature attaches itself to Melissa's eye, causing her agonising pain until Kat hits it with the broom and stamps on it. The story ends with the generator failing, plunging the room into darkness, with Kat then feeling the creature crawl onto her hand.
