What is the objective and objective elements of an Eighth Amendment claim for deliberate indifference to a serious medical need?

First, with respect to the objective element, plaintiff alleges that the denial of medical treatment for cirrhosis and hepatitis C caused him to suffer abdominal pain, liver pain, diarrhea, fatty liver, and the possibility of premature death. He has adequately alleged a sufficiently serious medical need. See Erickson v. Pardus, 551 U.S. 89, 93-94 (2007) (allegation that the denial of hepatitis C treatment resulted in endangerment of the plaintiff's life sufficiently meets the objective requirement for an Eighth Amendment claim based on deliberate indifference to a serious medical need).
