Plaintiff Jessie D. Duffield, proceeding pro se, brought a 42 U.S.C. § 1983 suit against several members of the medical staff at the James Crabtree Correctional Center (“JCCC”) in Helena, Oklahoma, claiming that they violated his Eighth Amendment right to be free from cruel and unusual punishment by showing deliberate indifference to his medical condition. After referring the case to a magistrate judge who issued a report and recommendation, the district court dismissed Mr. Duffield’s claim against some defendants and granted summary judgment in favor of others. Mr. Duffield appeals these dismissals and grants of summary judgment. Exercising jurisdiction under 28 U.S.C. § 1291, we affirm.
I. Background
Mr. Duffield, who has been an inmate in the custody of the Oklahoma Department of Corrections since February 26, 1999, was transferred to the JCCC on November 17, 2005. Soon after his transfer he began complaining of hip and lower back pain, and later he also complained of an ear infection. He sought medical attention for both ailments, and a series of examinations and treatments by JCCC physicians followed for the next year. Though he received treatment, Mr. Duffield alleges that he has not been treated in a “humane manner,” Complaint at 2, because the medical staff has failed to provide him the treatment and medication necessary to relieve the pain from his hip and lower back, has not sent him to an outside specialist who might prescribe a more effective course of treatment, and has provided such cursory treatment of his ear as to amount to “deliberate indifference.” Id. Mr. Duffield sued Dr. Michael Jackson, the medical director of the JCCC; Dr. Jeff Troutt, a JCCC doctor who attended to Mr. Duffield; Nurse Katryna Freeh, an administrator who facilitated Mr. Duf-field’s medical requests; Roy Arian, a Physician’s Assistant who attended to Mr. Duffield; and John Doe, the physicians and staff at the Oklahoma University Medical Center, where Mr. Duffield had a consultation with an ear specialist.
The district court referred Mr. Duf-field’s claim to a magistrate judge for preliminary review pursuant to 28 U.S.C. § 636(b)(1)(B). On October 30, 2007, the magistrate judge issued a Report and Recommendation in which he recommended that the defendants’ motions for dismissal and motions for summary judgment be granted. Specifically, he recommended that the claims against Dr. Jackson, Nurse Freeh, and John Doe be dismissed because Mr. Duffield had failed to allege that any *1237 of them was personally involved in the alleged deliberate indifference, and he recommended summary judgment for Mr. Arian and Dr. Troutt because Mr. Duffield had failed to produce evidence showing a genuine issue of material fact that either men had exhibited deliberate indifference. He also denied without prejudice Mr. Duf-field’s request for limited discovery for service and for appointment of counsel.
The magistrate judge’s Report and Recommendation ended with an explicit message to Mr. Duffield that advised him of his right to object to the report and the consequences of failing to do so:
The Plaintiff is advised of his right to file an objection to this Report and Recommendation with the Clerk of this Court by November 19, 2007, in accordance with 28 U.S.C. § 636 and Local Civil Rule 72.1. The Plaintiff is further advised that failure to make timely objection to this Report and Recommendation waives his right to appellate review of both factual and legal questions contained herein. Moore v. United States,950 F.2d 656 (10th Cir.1991).
Report and Recommendation at 35. The November 19, 2007 deadline came and went without any objection from Mr. Duf-field. On November 27, 2007, the district court entered an order that adopted the magistrate judge’s report and recommendation in its entirety. Three days later, on November 30, the court received an undated letter from Mr. Duffield in which he disputed some of the report’s factual findings and claimed that the Department of Corrections no longer had legal aides who could assist him. R. at 24. On December 11, Mr. Duffield filed a motion for a thirty-day extension in which to object to the Report and Recommendation. The district court denied his request, citing the fact that “the deadline for objection passed without a request for extension and ... Plaintiff was not diligent in seeking an extension.” Order of December 12, 2007. Mr. Duffield filed an objection to the denial of an extension on December 19, 2007, which the district court struck as repetitive on December 21. Mr. Duffield now appeals the final order, the order denying his extension of time, and the order striking his objection to the order denying an extension of time.
II. Analysis
A. Waiver of Appellate Review
Mr. Duffield disputes the factual findings recommended by the magistrate judge and adopted by the district court, arguing that there is a genuine issue of material fact as to whether the behavior of each defendant rose to the level of deliberate indifference to his medical conditions. The record unequivocally shows, however, that Mr. Duffield failed to timely object to the magistrate’s report. “[W]e have adopted a firm waiver rule when a party fails to object to the findings and recommendations of the magistrate.”
Moore v. United States,
Though Mr. Duffield is a pro se litigant, the magistrate judge was careful to inform him of both the time period for objecting and the consequences of failing to object, which we have held is sufficient.
See, e.g. Wardell v. Duncan,
We are also unpersuaded that the “interests of justice” exception demands that we overlook the waiver rule in Mr. Duffield’s case. Although “interests of justice” is “a rather elusive concept,”
Morales-Fernandez,
When we consider whether the importance of the issues raised might trigger the “interests of justice” exception, we have said that, “[i]n many respects, the interests of justice analysis we have developed, which expressly includes review of a litigant’s unobjected-to substantive claims on the merits, is similar to reviewing for plain error.”
Id.
To show plain error, Mr. Duffield would have to show “(1) error, (2) that is plain, which (3) affects substantial rights, and which (4) seriously affects the fairness, integrity, or public reputation of judicial proceedings.”
Id.
(quoting
United States v. Gonzalez-Huerta,
We cannot say that the decision in this ease to grant the defendants’ motions to dismiss and motions for summary judgment were plain error. For a prisoner to show that his lack of medical attention violated his Eight Amendment right to be free from cruel and unusual punishment, he must show “unnecessary and wanton infliction of pain.”
Estelle v. Gamble,
The magistrate identified ample undisputed evidence of medical attention that the JCCC staff gave to Mr. Duffield. He received repeated examinations from Dr. Troutt and Mr. Arian, underwent lab-work and x-rays, was prescribed several *1239 different medicines, and saw an outside specialist for his ear infection. Mr. Duf-field disagrees with some of the diagnoses and treatments and argues that they did not relieve the pain. Whether the JCCC staff was medically negligent is not the question, though; Mr. Duffield did not file a medical malpractice claim, he filed a § 1983 claim alleging cruel and unusual punishment.
Mr. Duffield also points to specific errors in the magistrate judge’s findings. He argues that the delay in sending him to the ear specialist, the failure to send him for a repeat examination by that specialist, and the failure to ever send him to an orthopedic specialist all show deliberate indifference. However, the “contention that he was denied treatment by a specialist is ... insufficient to establish a constitutional violation.”
Ledoux v. Davies,
Mr. Duffield also contests the factual findings by arguing that the defendants lied about providing him certain treatments — specifically, Rocephin injections for his ear. The magistrate judge considered Mr. Duffield’s allegation of lying, however, and determined that the records of these injections in the medical charts overwhelmed Mr. Duffield’s claim that he could not remember receiving the injections. Report at 32. He also found that even if Mr. Duffield had never received the injections, it would be immaterial to showing deliberate indifference, as he produced no evidence that the doctors knew he was not receiving the prescribed treatment. Id. Again, we cannot say that this finding was plain error.
Finally, we cannot say that it was plain error to dismiss the claims against Dr. Jackson, Nurse Freeh, and John Doe because Mr. Duffield had failed to allege personal participation in the deprivation of medical care. A § 1983 claim requires an “affirmative link,”
Green,
*1240 B. Denial of Motion for Extension
Mr. Duffield’s argument that the district court erred by denying his motion for a thirty-day extension in which to object to the magistrate judge’s Report and Recommendation, which would thereby enable him to preserve appellate review of the issues, also fails. Mr. Duffield did not file his motion until December 7, 2007, several weeks after the November 19 deadline to object had elapsed. Had he filed a more timely notice for extension, he perhaps would have received it, but we find no abuse of discretion by the district court in denying his untimely motion for an extension.
III. Conclusion
Accordingly, we AFFIRM the district court’s final order, order denying an extension of time, and order striking the objection to the order denying an extension of time. We DENY his motion to supplement the record on appeal. Mr. Duffield’s motion to proceed in forma pauperis is GRANTED, and we remind Mr. Duffield that he is obligated to continue making partial payments until the entire fee has been paid.
