OPINION
Sickle Cell Disease (“SCD”), also known as sicMe cell anemia, is a blood disorder that principally afflicts individuals of African and Indian descent. The disease leaves its victims easily fatigued and often suffering from episodes of acute pain. *561 SCD is particularly insidious because it rarely produces the objective medical evidence that cliniсians desire. In fact,
[p]atient[s] with SCD ... are in an almost uniquely disadvantaged position from the point of view of pain management. The condition is life threatening at times, yet patients are healthy between sickling episodes. Some individuals are affected by painful episodes much more than others, and pain is often the only or main symptom of an acute episode of illness.
James Elander & Kenny Midence, A Review of Evidence About Factors Affecting Quality of Pain Management in Sickle Cell Disease, 12(3) The Clinical J. of Pain 180-93 (Sept.1996). Because there is no way to demonstrate objectively that a SCD patient has pain, sufferers are often accused of “faking” their debilitating symptoms. Deborah G. Oster Pannell, Living With Sickle Cell Disease: From Suffering to Empoiverment, American Pain Society, http://www.ampainsoc.org/ pub/bulletin/jul99/advoeacy.htm (last visited May 19, 2006).
Appellee Jeffery Hines, an SCD patiеnt, applied for disability benefits based on his disease. The Social Security Administration (“SSA”) denied his claim largely because Mr. Hines’ claims of disabling pain were not supported by objective evidence. The district court reversed the SSA’s denial of benefits, and we affirm. Given the unique characteristics of the disease at issue in this case, we hold that the SSA Administrative Law Judge (“ALJ”) applied an improper standard to disregard the treating physician’s opinion that Mr. Hines was fully disabled. The ALJ also improperly relied on a vocational expert’s opinion that did not consider all relevant evidence in the record.
I.
Section 405(g) of Title 42 of the United States Code authorizes judicial review of the Social Security Commissioner’s denial of social security benefits.
Mastro v. Apfel,
II.
Mr. Hines was employed for 13 or 14 years as a railroad crew leader until his SCD became so severe that he could no longer work. (J.A. 122-23). Hе ceased work on April 6, 2001 upon advice from his treating physician, Dr. Myung Kil Jeon. (J.A. 79-80). Dr. Jeon has treated Mr. Hines’ SCD condition for approximately 17 years. Dr. Jeon determined that the chronic pain caused by Mr. Hines’ SCD is exacerbated by exertion and prevents Mr. Hines from maintaining steady employment. (J.A. 85, 90, and 156). In reports dated September 6, 2001, February 27, 2002, and July .5, 2002, Dr. Jeon stated that Mr. Hines was fully disabled by SCD.
Since leaving work in 2001, Mr. Hines has suffered from insomnia, has occasional blurred vision in his right eye, and experiences pain regularly. In addition to chronic pain, Mr. Hines has periodic acute pain crises which require approximately one month of recovery time. The record indicates that Mr. Hines was treated by *562 Dr. Jeon on September 24, 2001 and April 24, 2003 for acute sickle cell pain crises and on November 22, 2002 for generalized weakness, aching, and pain.
Mr. Hines regularly experiences fatigue due to a combination of his SCD and insomnia. The fatigue prevents him from performing many everyday tasks. For example, when Mr. Hines attempts to mow his lawn, he is unable to complete the job in one effort and is forced to lie down. Indeed, Mr. Hines testified that his condition forces him to lie down and rest approximately half of every day, and he is able to attend church only two to three times per month. (J.A. 133). At the ALJ hearing, Mr. Hines’ wife testifiеd that he is not able to do much around the house, he is forgetful, he does not leave the house for trips or visiting friends, and “a lot of time he have a lot of pains in his leg.” (J.A. 139). This evidence was unrebutted.
Mr. Hines’ disability insurance company referred him to Dr. Rupa Redding-Lallinger (“Dr. Lallinger”), a hematologist, for an evaluation of his SCD. Dr. Lallinger noted there was no objective evidence of “major end-organ damage in the bones, although it is possible for early avascular necrosis not to show up on plain films, but be apparent in an MRI. No sign of recurrent bony infarction to explain his frequent pain.” (J.A. 66). Dr. Lallinger then qualified his observation by stating that “[i]t must be noted, however, that with pain from sickle cell disease there are no confirmatory laboratory or radiologic tests that will prove or disprove whether a patient is having pain.” (J.A. 66).

“Disability” is the “inability to engage in any substantial gаinful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.” 42 U.S.C. § 423(d)(1)(A). The “[djetermination of eligibility for social security benefits involves a five-step inquiry.”
Walls v. Barnhart,
whether (1) the claimant is engaged in substantial gainful activity; (2) the claimant has a medical impairment (or combination of impairments) that are severe; (3) the claimant’s medical impairment meets or exceeds the severity of one of the impairments listed in Appendix I of 20 C.F.R. Part 404, subpart P; (4) the claimant can perform her past relevant work; and (5) the claimant can perform other specified types of work.
Johnson v. Barnhart,
The ALJ found that Mr. Hines satisfied steps one and two of the inquiry. At the third step of his inquiry, the ALJ concluded that Mr. Hines’ SCD did not meet or excеed the severity of the qualifying impairments recognized in an Appendix to the regulations. The ALJ therefore sought to determine Mr. Hines’ Residual Functional Capacity (“RFC”) for employment.
RFC is a measurement of the most a claimant can do despite his limitations. See 20 C.F.R. § 404.1545(a). According to the Social Security Administration,
RFC is an assessment of an individual’s ability to do sustained work-related physical and mental activities in a work setting on a regular and continuing basis. A ‘regular and continuing basis’ means 8 hours a day, for 5 days a week, or an equivalent work schedule.
Social Security Regulation (SSR) 96-8p (emphasis added). RFC is to be determined by the ALJ only after he considers *563 all relevant evidence of a claimant’s impairments and any related symptoms (e.g., pain). See 20 C.F.R. § 404.1529(a).
The ALJ concluded that Mr. Hines had the RFC “to perform a wide range of sedentary work with limitations to working in temperature extremes, working at a production rate, or performing more than simple, routine, repetitive tasks.” (J.A. 151). In light of SSR 96-8p, this conclusion implicitly contained a finding that Mr. Hines physically is able to work an eight hour day.
Having concluded that Mr. Hines had the RFC to perform a sedentary job, the ALJ then evaluated Mr. Hines’ case at the fifth step of the inquiry. 1 This step requires the Commissioner to prove that a significant number of jobs exist which the claimant could perform, despite his impairments.
The ALJ found that the Commissioner carried her burden of proving that Mr. Hines could perform certain jobs in the national economy. In reaching this conclusion, the ALJ relied on the opinion of Steven D. Carpenter, a vocational expert who had never met Mr. Hines. The vocational expert assumed that Mr. Hines could work a full eight hour day. Based on this assumption, the vocational expert opined that “claimant could work as an order clerk ..., call out operator ..., and laundry priсing clerk.” (J.A. 143). He testified that significant numbers of these jobs exist in the North Carolina economy.
A.
We begin by reviewing the ALJ’s finding that Mr. Hines has the RFC “to perform a wide range of sedentary work with limitations ...” for a full eight hour work day.
See
SSR 96-8p. In reaching this conclusion, the ALJ improperly refused to credit Dr. Jeon’s medical opinion that his long term patient (Mr. Hines) was totally disabled. The ALJ was obligated to evaluate and weigh medical opinions “pursuant to the following nоn-exclusive list: (1) whether the physician has examined the applicant, (2) the treatment relationship between the physician and the applicant, (3) the supportability of the physician’s opinion, (4) the consistency of the opinion with the record, and (5) whether the physician is a specialist.”
Johnson v. Barnhart,
The ALJ refused to credit Mr. Hines with having debilitating pain because a laundry list of objective indicators did not appear in Dr. Jeon’s medical records. For example, the ALJ observed that there was no evidence of end-organ damage to Mr. Hines’ kidneys or bones, neurological deficits, swollen joints or extremities, muscle аtrophy, or decreased range of motion in Mr. Hines’ joints. The ALJ applied an incorrect legal standard when he required objective evidence of pain. Essentially, the ALJ required objective evidence that Mr. Hines’ pain was so intense as to pre *564 vent him from working an eight hour day. This was in error.
Disagreements over the role of subjective evidence in proving pain are not a recent development. The late Judge K.K. Hall once observed that “[t]his circuit has battled the [Commissioner] for many years over how to evaluate a disability claimant’s subjective complaints of pain.”
Mickles v. Shalala,
On appeal, the claimant first contends that the Secretary improperly evaluated his complaints of pain. We agree. The ALJ concluded that the claimant’s subjective complaints of pain and allegations of disability were not corroborated by the preponderance of the medical evidence as to the severity and frequency of his symptoms and limitations. We have held that pain itself can be disabling, and it is incumbent upon the ALJ to evaluate the effect of pain on a claimant’s ability to function. Further, while there must be objective medical evidence of some condition that could reasonably produce the pain, there need not be objective evidence of the pain itself or its intensity.
Id. at 49 (emphasis added).
Despite our holdings in
Walker
and its predecessors, the Commissioner continued to require objective clinical evidence of the existence and intensity of a claimant’s pain. In a class action suit initiated by social security disability claimants, this Court affirmed a finding that the SSA willfully refused to acquiesce to Fourth Circuit precedent.
Hyatt v. Heckler,
This Ruling supersedes, only in states within the Fourth Circuit (North Carolina, South Carolina, Maryland, Virginia and West Virginia), Social Security Ruling (SSR 88-13), Titles II and XVI: Evaluation of Pain and Other Symptoms:
FOURTH CIRCUIT STANDARD:
Once an underlying physical or ental (sic) impairment that could reasonably be expected to cause pain is shown by medically acceptable objective evidence, such as clinical or laboratory diagnostic techniques, the adjudicator must evaluate the disabling effects of a disаbility claimant’s pain, even though its intensity or severity is shown only by subjective evidence. If an underlying impairment capable of causing pain is shown, subjective evidence of the pain, its intensity or degree can, by itself, support a finding of disability. Objective medical evidence of pain, its intensity or degree (i.e., manifestations of the functional effects of pain such as deteriorating nerve or muscle tissue, muscle spasm, or sensory or motor disruption), if available, should be obtained and considered. Because pain *565 is not readily susceptible of objective proof, however, the absence of objective medical evidence of the intensity, severity, degree or functional effect of pain is not determinative.
Social Security Ruling (SSR) 90-lp (emphasis added),
superseded by
SSR 96-7p (“If an individual’s statements about pain or other symptoms are not substantiated by the objective medical evidence, the adjudicator must consider- all of the evidence in the casе record, including any statements by- the individual and other persons concerning the individual’s symptoms.”);
see
20 C.F.R. §§ 416.929(c)(1) and (c)(2). SSR 90-lp and its successors establish a two step process that comports with applicable Fourth Circuit precedent.
Hunter v. Sullivan,
The record in this case demonstrates that Mr. Hines complied with the two step process mandated by Fourth Circuit precedent and the resulting regulations.
See Mickles,
Having met his threshold obligation of showing by objective medical evidence a condition reasonably likely to cause the pain claimed, Mr. Hines was entitled to rely exclusively on subjective evidence 3 to prove the second part of the test, i.e., that his pain is so continuous and/or so severe that it prevents him from working a full eight hour day. 4 Mr. Hines did so by testifying that his illness.and the resulting fatigue require him to lie down “half a day.” Also, his wife testified that Mr. Hines is forgetful, unable to do much around the house, and has “a lot of pains in his leg.” Claimant’s friend, Mr. Ernest Nixon, tеstified that Mr. Hines suffered from a “lack of energy” and that his energy level is “not the energy he used to have.” (J.A. 141).
In determining that Mr. Hines had the RFC to perform a sedentary job, the ALJ discredited the above described testimony as inconsistent with Mr. Hines’ testimony about his daily activities. This conclusion was not supported by substantial evidence because the record, when read as a whole, reveals no inconsistency between the two. The ALJ selectively cited evidence concerning tasks which Mr. Hines was capable of performing:
[t]he claimant also noted that he rakes his yard and occasionally does repairs *566 such as fixing a door knob. He reported that he visited family and ... he indicated ... that he cut the grass was active in his church as a deacon, visited the sick and relatives, and went out to eat.
(J.A. 151).
This recitation of the evidence ignores Mr. Hines’ further testimony thаt he has pain “mostly all the time” and that taking Darvocet “mak[es] it feel better and it’s not really gone.” When asked what he does for the pain other than take medication, Mr. Hines stated, “[w]ell, I get up and I do some things around the house. Rakes the yard or tries mowing the grass and when I start to feel bad I stop and finish up — maybe try to finish up the next day or whatever.” (J.A. 130). Additionally, the ALJ disregarded Mr. Hines’ qualification of his activity levels in which he described that “рrobably” he would “try to fix ... a doorknob” as one of his chores around the house. (J.A. 133). Mr. Hines also listed “Church” as his only social outlet or activity that he attends two to three times per month. (J.A. 133).
The deference accorded an ALJ’s findings of fact does not mean that we credit even those findings contradicted by undisputed evidence.
See Diaz v. Chater,
B.
“[I]n order for a vocational expert’s opinion to be relevant or helpful, it must be based upon a consideration of all other evidence in the record, and it must be in response to proper hypothetical questions which fairly set out all of claimant’s impairments.”
Walker,
In rendering his opinion that there are thousands of jobs in North Carolina available to Mr. Hines, the vocational expert assumed that Mr. Hines was capable of working an eight hour day. As discussed above, there was no evidence of this in the record, and the evidence to the contrary was unrebutted. 5
To his credit, the vocational expert acknowledged the absence of employment opportunities for individuals who can work no more than four hours a day. The ALJ asked a question on this point and the vocational expert answered it as follows:
Q Now, I want you to further assume that the individual has all the limitations that’s been described in the testimony here today. Especially the testimony about the Claimant having to lie down half the time during the day as he described either due to his fatigue or to sleep since he only gets four hours of sleep a night. And all the rest of the testimony. Could that individual engage in these jobs or any other jobs you could suggest?
A No. Not having to lie down for several hours daily. He wouldn’t be able to meet any type of work performance demand.
(J.A. 144).
Mr. Hines’ attorney then questioned the vocational expert as follows:
*567 Q And with — I believe for instance when he testified about his severe attack and the recovery from that just to get back to baseline being a month how would that type of complete inability to report to a job absenteeism affect his ability to hold any type of job?
A Being out a month at a time it would probably eliminate his ability to meet the generally accepted attendance requirements of any job.
(J.A. 145).
The instant case is analоgous to this Court’s previous decision in
Crider v. Harris,
The vocational expert in the instant case confirmed that lying down for a portion of the day would еxclude the employment alternatives. The vocational expert also agreed that Mr. Hines’ month-long recoveries from acute pain attacks would probably prevent him from complying with the attendance policy of “any” job. (J.A. 145). Because the vocational expert did not take into account all facts in the record when rendering his opinion of employability, that opinion had no value.
We notе in this regard that it is the Commissioner, not Mr. Hines, who bears the evidentiary burden of proving that Mr. Hines remains able to work other jobs available in the community.
Grant v. Schweiker,
IV.
The district court properly reversed the ALJ’s ruling and awarded disability benefits to Mr. Hines. The ALJ applied an improper legal standard to discredit the treating physician’s opinion and refused to credit unrebutted testimony that plaintiff could not work an eight hour day. Finally, the ALJ relied upon expert testimony that lacked a factual foundation. Because the record establishes Hines’ entitlement to benefits, we will award benefits without remand.
See Crider,
AFFIRMED.
Notes
. At step four of the inquiry, the ALJ concluded that Mr. Hines was not capable of performing his past work as a railroad conductor. (J.A. 152).
. The treating physician rule is not absolute. An “ALJ may choose to give less weight to the testimony of a treating physician if there is persuasive contrary evidence.”
Hunter v. Sullivan,
. While objective evidence is not mandatory at the second step of the test,
[tjhis is not to say, however, that objective medical evidence and other objective evidence are not crucial to evaluating the intensity and persistence of a claimant's pain and the extent to which it impairs her ability to wоrk. They most certainly are. Although a claimant’s allegations about her pain may not be discredited solely because they are not substantiated by objective evidence of the pain itself or its severity, they need not be accepted to the extent they are inconsistent with the available evidence, including objective evidence of the underlying impairment, and the extent to which that impairment can reasоnably be expected to cause the pain the claimant alleges she suffers.
Craig v. Chater,
. Dr. Jeon opined that Mr. Hines’ pain not only prevents him from working, but that working exacerbates the level of pain that he already experiences. (J.A..85, 90, and 156).
. In order to formulate an opinion, the vocational expert must assume as true the RFC determined by the ALJ. As discussed supra, the RFC determined by the ALJ and relied upon by the vocational expert in this case is erroneous.
