Anne R. HILL, Plaintiff-Appellant, v. Carolyn W. COLVIN, Acting Commissioner of Social Security, Defendant-Appellee, 807 F.3d 862

WILLIAMS, Circuit Judge. An administrative law judge disbelieved Anne Hill’s testimony that she could not sit, stand, or walk for extended periods of time and denied her application for Disability Insurance Benefits and Supplemental Security Income. In this action arising under 42 U.S.C. § 405(g), Hill challenges this adverse credibility finding as well as the ALJ’s assessment of her residual functional capacity. We agree with Hill that the ALJ’s credibility analysis was flawed and remand the case to the agency for further proceedings. I. BACKGROUND A.

Evidence of Hill’s Disabilities Hill, who is currently 56 years old, worked for more than 13 years at a steel factory, where her duties included lifting and carrying steel sheets that weighed up to 100 pounds. The manual labor took a toll on Hill’s body, and, unable to keep working at the factory, she applied for disability benefits in July 2011. She alleged an onset date in June 2011 and listed eight impairments: a total hip replacement, a recommended total shoulder replacement, carpal tunnel, a ruptured disc, cervical fusion, knee pain, a broken left hand, and tendinitis.

Hill had cervical-fusion surgery in 1985, but there is no mention of neck pain in her available medical records before November 2010. In November 2010, she was diagnosed with neck strain, though she was cleared for work without restrictions. The next month, she saw a doctor for shoulder pain.

Imaging studies revealed a likely hyperextension injury; a bone spur; tears of the tendons in her left shoulder, left bicep, and left hip joint; a possible “loose body” in her left shoulder; osteoarthritis in her left hip; and tendinopathy in her left shoulder: She was prescribed pain medication and her arm was placed in a sling. During a follow-up appointment with orthopedic surgeon Dr. Barry Liechty, Hill reported improvement but also said that she still experienced pain in her shoulder. Hill met with Dr. Liechty again in May 2011, complaining of pain in her left hip, knee, and groin. Dr.

Liechty noted severe osteoarthritis of the left hip and performed a total hip replacement two months later. A few weeks after that surgery, Dr. Liechty reported that Hill was limping and taking one or two Vicodin each week. He recommended that she not work at a job requiring pulling, pushing, or squatting.

He also recommended that she not lift more than 10 pounds, but that recommendation was changed a few weeks later to restrict only “heavy lifting.” Nearly two months after her hip replacement, in August 2011, Hill met with state-agency doctor David Ringel, an osteopathic physician, who noted that Hill limped and had “quite a bit of stiffness.” Dr. Ringel reported that Hill said she could lift 10 pounds, do most household chores, and stand 1 to 2 hours at a time and 4 hours total during an 8-hour workday.

He described Hill as mildly obese' and noted some limitations in her ability to move her shoulders, neck, lower back, and left hip. The next month, in September 2011, another state-agency doctor, Dr. J. Sands, reviewed Hill’s medical records and prepared a Physical Residual Functional Capacity Assessment. Dr. Sands noted Hill’s history of shoulder and 'hip osteoarthritis. He opined that her “hip replacement would be expected to improve with further therapy and time,” but said that she would be limited to occasional pulling, pressing, and pushing with her left extremities.

He estimated that Hill could lift 20 pounds occasionally and 10 pounds frequently, and could sit, stand, or walk 6 hours each in an 8-hour workday. Dr. Sands further opined that Hill occasionally could balance, stoop, kneel, crouch, crawl, and climb ramps and stairs, but could not climb ladders, ropes, or scaffolds. Two weeks later Hill complained of low back pain, and an imaging study revealed minimal degenerative disc disease, narrowing disc spaces, atherosclerotic vascular changes, and calcification of a portion of the pelvis. Dr.

Sands and two additional state-agency physicians reviewed this new information but concluded that it did not change the earlier assessment of Hill’s impairments. The Social Security Administration initially denied Hill’s application in October 2011, and did so again on reconsideration the next month. In September 2012, Hill testified before the ALJ. She explained that she had to stop working at the factory because, after her hip-replacement surgery, she could no longer perform manual labor.

Hill said that, despite taking aspirin and Naproxen, she could “hardly sleep at night” because of shoulder and neck pain, and she had trouble walking because of leg and back pain.

But, Hill explained, it was difficult for her to determine the source of the pain because “[fit’s all connected somehow.” She added that she no longer took narcotic pain relievers because her doctor was concerned that she could become addicted. (That concern may have been caused by Hill’s admission of “heavy” drinking and a family history of alcoholism.) Hill then explained that she lacked health insurance and could not afford to go a doctor “over every little pain,” nor could she afford the total shoulder replacement her doctor had recommended.

She described her daily activities, which then included babysitting, caring for her pets and her roommate (who is an amputee), going to church, visiting with family members, and doing chores like loading the dishwasher, vacuuming, taking out the garbage, and doing laundry. But she added that she needs to take breaks while performing those chores and that she is unable to lift the .child she babysits.

She estimated that she could sit or stand for about 10 to 15 minutes without a break, lift between 10 and 15 pounds with her right arm but much less with her left, squat or kneel with her right leg but not with her left, and slowly crawl. Hill rated her hip pain at 3 out of 10, her shoulder pain at 8, and her leg pain at 5. A longtime friend, Kim Stamate, testified that she helps walk Hill’s dogs and carry Hill’s groceries, and that she had not seen Hill walk without a limp in the past year.

A vocational expert testified that Hill could not perform her past work if limited to the extent described by the ALJ: able to lift up to 20 pounds occasionally and 10 pounds frequently; able to sit, stand, or walk for 6 hours each in an 8-hour workday; occasionally able to balance, stoop, kneel, crouch, crawl, and climb ramps and stairs, but never able to climb ladders, ropes, or scaffolds; and limited to occasional pulling, pushing, and reaching with the left extremities.

But, the VE continued, Hill still could work at jobs classified as light and unskilled, such as a dealer account investigator, a furniture rental consultant, and a counter clerk. In the national economy, the VE said, there were 22,000 jobs as a dealer account investigator, 40,000 jobs as a furniture rental consultant, and 50,000 jobs as a counter clerk. Those jobs, the VE asserted, would be available to a person who was unable to crouch or to push, reach, or pull with her left extremities.

Finally, the VE testified that someone with Hill’s limitations, if also unable to stand or walk more than 2 hours in an 8-hour workday or lift more than 10 pounds occasionally, still could perform sedentary jobs, see SSR 83-10, 1983 WL 31251, at *5; 20 C.F.R. §§ 404.1567(a), 416.967(a), like a call-out operator (45,000 jobs in the national economy), a semiconductor bonder (30,000 jobs in the national economy), and a registration clerk (27,000 jobs in the national economy). B. The Agency’s Decision The ALJ concluded that Hill is not disabled.

The ALJ applied the 5-step analysis for assessing disability, see 20 C.F.R. §§ 404.1520(a)(4), 416.920(a)(4), and first determined at Step 1 that Hill had not engaged in substantial gainful activity since her alleged onset in June 2011. At Step 2 the ALJ identified Hill’s severe impairments as degenerative joint disease with total replacement of the left hip and osteoarthritis of the left shoulder.

The ALJ also concluded, however, that Hill’s alleged back and neck pain do not cause “more than minimal functional limitations” and “do not further reduce her capacity beyond the limitations imposed by her left hip and left shoulder impairments.” The ALJ reasoned that, because Hill had worked at a job involving manual labor “for many years” after her neck surgery and had a full range of motion in her neck in December 2010, her neck pain likely had resolved before her alleged onset date in June 2011.

As for Hill’s back, the ALJ noted that the imaging study done in October 2011 had “revealed only minimal degenerative changes,” which, according to the ALJ, “would not be expected to cause significant pain without any nerve root impingement or spinal steno-sis.” What’s more, the ALJ added, Hill had “not had any epidural injections, physical therapy, or other treatment for low back pain,” did not have an abnormal gait, and had “not been evaluated by a specialist for low back pain.” At Step 3 the ALJ concluded that none of Hill's impairments, individually or in combination, satisfy a listing for presumptive disability.

At Step 4 the ALJ rejected Hill’s account of the severity of her disabling limitations.

The ALJ started with boilerplate language reciting that Hill’s “statements concerning the intensity, persistence and limiting effects of these symptoms are not entirely credible” even though her “medically determinable impairments could reasonably be expected to cause the alleged symptoms.” The ALJ then asserted that Hill’s hip pain had improved significantly since her surgery: Hill had decreased her use of pain medication; she did not use a walker; her doctor had cleared her for work with minimal limitations; she had not complained in her most recent visits with doctors of hip, leg, or back pain; and her doctor had reported that Hill’s “gait was not abnormal.” Turning next to Hill’s alleged back pain, the ALJ repeated that an imaging study had shown “only minimal degenerative changes in the lumbar spine” and that “[w]ithout any nerve root compression, loss of disc space height, or spinal stenosis, the extent of low back pain and inability to sit, stand, and walk alleged by the claimant is not credible, particularly in light of the absence of complaints of low back pain to treating physicians.” And, concerning Hill’s neck pain, the ALJ again asserted that the lack of any complaints of pain to doctors after November 2010 “suggests that the neck pain resolved quickly.” Concerning Hill’s shoulder, however, the ALJ acknowledged that Hill’s testimony was supported by evidence of osteoarthritis and tendinopathy in the medical records.

But the ALJ concluded that, although Hill’s use of her left arm was limited, she still could use her right arm to lift and carry 20 pounds occasionally and 10 pounds frequently. Hill’s ability to complete some housework, the ALJ insisted, confirmed that her use of her right arm was not limited. And, the ALJ added, Hill’s use of only aspirin and Naproxen for pain “suggests that the pain is not as limiting” as she testified. The ALJ gave great weight to the medical opinions of Hill’s treating orthopedist and the state-agency physicians who suggested that she could perform a limited range of light work.

But the ALJ discounted the testimony of Hill’s friend, Sta-mate, reasoning that she was not a “trained medical observer” and had contradicted the observations of Hill’s doctor. The ALJ noted also that Hill “wanted to work but could not find someone to hire her.” Finally, at Step 5 the ALJ concluded that Hill could not perform her past relevant work but could perform light work, including as a dealer account investigator, furniture rental consultant, or counter clerk. Finding those jobs existed in significant numbers, the ALJ found Hill not disabled.

The Appeals Council denied review, making the ALJ’s decision the final decision of the Commissioner. See Pepper v. Colvin, 712 F.3d 351, 361 (7th Cir.2013). The district judge upheld that decision. II. ANALYSIS In this court Hill challenges the adverse credibility finding, arguing that the ALJ improperly discredited her testimony that back and neck pain limit her ability to stand, sit, and walk for extended periods of time. We agree. As discussed below, the ALJ’s analysis was flawed in several respects.

First, the ALJ reasoned that Hill’s credibility was undermined because she had stopped taking narcotic pain relievers and had complained of back pain to doctors only intermittently. Yet the ALJ ignored explanations for the conservative treatment: Hill testified that her doctor was worried about the addictiveness of narcotic pain relievers and that her back and neck pain may have been related to her shoulder and hip pain, which she did complain about to doctors on multiple occasions.

See SSR 96-7P, 1996 WL 374186, at *7 (ALJs must consider “any explanations that the individual may provide, or other information in the case record, that may explain infrequent or irregular medical visits or failure to seek medical treatment”); Beardsley v. Colvin, 758 F.3d 834, 840 (7th Cir.2014) (remanding to agency where ALJ made no attempt to determine reason for conservative treatment).

The ALJ acknowledged Hill’s testimony that she could not afford to visit doctors frequently, but nonetheless found Hill’s testimony about back pain not credible because Hill “did not even seek a referral to a back specialist.” How Hill would have paid for a specialist, the ALJ did not say. See Craft v. Astrue, 539 F.3d 668, 679 (7th Cir.2008) (ALJ should have considered claimant’s “inability to pay for regular treatment and medicine”). Second, the ALJ reasoned that Hill was exaggerating her back pain because she had never been diagnosed with nerve root compression, loss of disc space height, or spinal stenosis.

The ALJ’s conclusion is not supported by any medical evidence in the record; it amounts to the ALJ improperly “playing doctor.” See Engst-rand v. Colvin, 788 F.3d 655, 660-61 (7th Cir.2015); Goins v. Colvin, 764 F.3d 677, 680 (7th Cir.2014); Pate-Fires v. Astrue, 564 F.3d 935, 946-47 (8th Cir.2009). Third, the ALJ reasoned that Hill was stretching the truth about her neck pain because she still wanted to work, and because she performed manual labor for many years after her neck surgery.

This logic is backward: a “claimant with a good work record is entitled to substantial credibility when claiming an inability to work because of a disability.” Rivera v. Schweiker, 717 F.2d 719, 725 (2d Cir.1983); see Singletary v. Sec’y of Health, Educ. & Welfare, 623 F.2d 217, 219 (2d Cir.1980) (claimant’s history of performing demanding work over long hours “justifies the inference that when he stopped working he did so for the reasons he testified to”); Allen v. Califano, 613 F.2d 139, 147 (6th Cir.1980).

And, as we have explained, a claimant’s desire to work is not inconsistent with her inability to work because of a disability. See Voigt v. Colvin, 781 F.3d 871, 876 (7th Cir.2015) (claimant’s desire to work, but inability to find work, is “consistent with his wanting to lead a normal life yet being unable to land a job because he’s disabled from gainful employment”); Jones v. Shalala, 21 F.3d 191, 192 (7th Cir.1994) (explaining that claimant might be earning a decent wage despite being permanently disabled).

The Commissioner 'Counters that consideration of a claimant’s work history is “proper when the claimant has had essentially the same condition for decades, and remained able to work.” That statement is true enough, see Orlando v. Heckler, 776 F.2d 209, 213-14 (7th Cir.1985); Genier v. Astrue, 606 F.3d 46, 49 (2d Cir.2010); Johnson v. Apfel, 240 F.3d 1145, 1148-49 (8th Cir.2001), but Hill has never asserted that the severity of her impairments have remained the same for decades.

Hill contends instead that she gradually experienced worsening health problems that eventually became disabling in June 2011, shortly before she applied for benefits. Indeed, the ALJ found that Hill suffers from degenerative joint disease (osteoarthritis), which often grows more severe with the passage of time. See Roddy v. Astrue, 705 F.3d 631, 637 (7th Cir.2013) (ALJ’s reasoning flawed because it ignored the fact that “degenerative” conditions get worse over time).

At oral argument, counsel for the Commissioner attempted .to liken Hill’s activities of daily living, particularly babysitting, with working full time. But Hill’s home life was not a reason given by the ALJ for denying benefits and so not a proper basis for us to uphold the ALJ’s decision. See Sec. & Exch. Comm’n v. Chenery Corp., 318 U.S. 80, 87, 63 S.Ct. 454, 87 L.Ed. 626 (1943); Hanson v.

Colvin, 760 F.3d 759, 762 (7th Cir.2014). (The ALJ addressed Hill’s home activities only to the extent that they showed that she had use of her right arm.) Counsel’s reasoning is unsound, in any event, because we have repeatedly warned against equating the activities of daily living with those of a full-time job. See Bjornson v. Astrue, 671 F.3d 640, 647 (7th Cir.2012); Spiva v. Astrue, 628 F.3d 346, 352 (7th Cir.2010). It might be argued that these mistakes in evaluating Hill’s credibility were harmless.

As the Commissioner points out, no doctor has opined that Hill has more limitations than the ALJ incorporated into her assessment of Hill’s residual functional capacity. But Hill testified that she is more limited, and her testimony cannot be disregarded simply because it is not corroborated by objective medical evidence. See Hall v. Colvin, 778 F.3d 688, 691 (7th Cir.2015); Pierce v. Colvin, 739 F.3d 1046, 1049-50 (7th Cir.2014); Robbins v. Soc. Sec. Admin., 466 F.3d 880, 883 (9th Cir.2006).

We are not confident that the ALJ would have reached the same conclusion about Hill’s credibility had she not inappropriately “played doctor,” ignored possible explanations for Hill’s conservative treatment, and conflated a desire to work with the ability to do so. So the ALJ’s errors are not harmless. See McKinzey v. Astrue, 641 F.3d 884, 892 (7th Cir.2011) (explaining that error is harmless only if court is “convinced” that ALJ would reach same result on remand); Spiva, 628 F.3d at 353 (error is not harmless simply because ALJ might have reached the same result absent the error). III.

CONCLUSION We REVERSE the district court’s judgment and REMAND this case to the Commissioner for further proceedings. . The parties did not tell us what "cervical fusion” is, but they should, have. This case is not a dispute about the meaning of an uncommon term or term of art. But parties should define this kind of term even if its meaning is not in dispute and does not drive the outcome. Doing so makes the case more understandable and gives clarity to readers. We have included some

definitions to make this opinion more understandable; but they were not necessary to the outcome. "Cervical fusion” is a surgery that joins bones in the neck. See Cervical Spinal Fusion, WebMD, www. webmd.com/back-pain/cervical-spinal-fusion (visited October 27, 2015, as were the other websites cited in this opinion). . "Tendinopathy" is another term that should have been defined for clarity. It refers to both: (1) inflammation of a tendon; and (2) small tears in a tendon. See Tendon Injury (Tendinopathy), WebMD, www.webmd.com/ hw-popup/tendon-injuries-tendinopathy. .

Atherosclerosis is a hardening and narrowing of the arteries. See Heart Disease and Atherosclerosis, WebMD, www.webmd.com/ heart-diseas e/guide/atherosclerosis-faq. . Light work requires standing or walking for about 6 hours in an 8-hour workday and sitting during the remainder. See SSR 83-10, 1983 WL 31251, at *5-6; 20 C.F.R. §§ 404.1567(b), 416.967(b). .

A dealer account investigator is defined in the Dictionary of Occupational Titles as a person who ’ "[v]isits dealers to verify purchases financed by [a] bank against physical inventory of merchandise.” Investigator, Dealer Accounts (financial), Dictionary of Occupational Titles, www.oalj.dol.gov/PUBLIC/ DOT/REFERENCES/DOT02B.HTM. . This job is described in the DOT's last update (in 1991) as processing film for photo printing. Counter Clerk (photofinishing), Dictionary of Occupational Titles, www.oalj.dol. gov/PUBLIC/DOT/REFERENCES/DOT02C. HTM. .

A call-out operator "[cjompiles credit information, such as status of credit accounts, personal references, and bank accounts to fulfill subscribers' requests, using telephone.” Call-Out Operator (business ser.; retail trade), Dictionary of Occupational Titles, www.oalj. dol.gov/PUBLIC/DOT/REFERENCES/DOT02 B.HTM. .

This job involves operating an "automatic bonding machine that bonds gold or aluminum wire to integrated circuit dies to connect circuitry to package leads.” Bonder, Semiconductor (electron, comp.), Dictionary of Occupational Titles, www.oalj.dol.gov/PUBLIC/ DOT/REFERENCES/DOT07C.HTM. .The VE gave DOT number 205.367-030 for "registration clerk.” That's the number for an election clerk — someone who performs administrative tasks during elections. See Election Clerk (government ser.), Dictionary of Occupational Titles, www.oalj.dol.gov/PUBLIC/ DOT/REFERENCES/DOT02A.HTM.

There are two jobs in the DOT titled "registration clerk.” A registration clerk may conduct interviews "to compile information for legal or other records," Registration Clerk (government ser.), Dictionary of Occupational Titles, www. oalj.dol.gov/PUBLIC/DOT/REFERENCES/ DOT02A.HTM, or record identifying information from library patrons on cards and microfilm, Registration Clerk (library), Dictionary of Occupational Titles, www.oalj.dol.gov/ PUBLIC/DOT/REFERENCES/DOT02C.HTM. . Additionally, we note our serious concerns with the vocational expert's testimony (addressed further in the concurring opinion).

It was improper for the vocational expert to rely on his own unspecified "experience” in arriving at his conclusions about what work Hill could do without using her left arm. See Herrmann v. Colvin, 772 F.3d 1110, 1113 (7th Cir.2014); Browning v. Colvin, 766 F.3d 702, 709 (7th Cir.2014). And the vocational expert should have explained the source and accuracy of his data concerning the number of available jobs. See Alaura v. Colvin, 797 F.3d 503, 507-08 (7th Cir.2015); Voigt, 781 F.3d at 879; Browning, 766 F.3d at 709.

We are skeptical, for example, about how many jobs exist today that involve maintaining library records on microfilm. Cf. Alaura, 797 F.3d at 508 (expressing skepticism that 200,000 people in the United States work addressing mail by hand or typewriter).
