MEMORANDUM OPINION AND ORDER
Casey Ostrowski seeks judicial review of the decision of the Secretary of Health and Human Services (“the Secretary”) denying him disability benefits under Titles II and XVI of the Social Security Act. 42 U.S.C. § 401 et seq. (Title II or “SSDI”); § 1381 et seq. (Title XVI or “SSI”). The parties have filed cross-motions for summary judgment. Because the decision of the Secretary contains errors of law and is not supported by substantial evidence, we vacate the denial of benefits and remand for further proceedings.
I.
The following is a brief summary of the facts as revealed by the administrative record. We will develop other facts as they become relevant to the legal issues raised by Ostrowski’s appeal.
Ostrowski is now 41 years old. From 1966 to 1980 he worked at several jobs, including bus driver, medical courier, and production control. He held most of his jobs for no more than a few months each, and has not worked since February, 1980. He claims he is disabled because of severe back pain and of severe psychological problems. Both problems have a long history.
He first had back surgery, a “lumbar laminectomy,” in 1975. In late 1980 he exacerbated his condition, and was experi*1112encing severe pain. In January, 1981 he had a second laminectomy at Lakeside V.A. Hospital for a herniated nucleus pulposus at L4-L5. While his condition admittedly improved following this operation, he continued to experience recurrent severe pain, and was admitted to Lakeside V.A. in June, 1981, and was treated again for pain in August, 1982, but there was no evidence then of radiculopathy or sciatica. His examination in August, 1981 by the Consultative Examiner hired by the Secretary revealed degenerative disc disease at L4-L5 and minimal osteoarthritis. He could walk with a slight limp for about two blocks, had good muscle strength, and somewhat limited flexibility. None of the various doctors who examined him expressed doubt that Ostrowski was experiencing pain or that this pain lacked a basis in an observable medical condition.
Ostrowski testified at his Administrative Law Judge (“AU”) hearing on October 27, 1982 that his back pain is severe and is felt in his neck and legs as well. He generally does not leave his house for more than a few hours at a time; does very little housework; cannot sit for more than two or three hours; and has difficulty driving, bending or stooping. He spends much of his time watching television. At other times during the last few years he had been able to do some housework and driving. His pain appears to have been varied in severity.
Ostrowski’s emotional problems have also lasted many years. He has been in and out of mental institutions at least ten times since 1965. That year he was hospitalized for a type of paranoid psychosis. In 1968, he was hospitalized for “a nervous breakdown.” In 1971 and 1973, he was hospitalized for depression. In 1974 he was treated for an unknown psychiatric disorder. In 1979 he was again hospitalized for depression, and a second time for an unknown disorder. In February, 1980 he was hospitalized for bipolar affective disorder, and again in June, 1980 for an unknown disorder. In September, 1980 he was hospitalized for two months for bipolar affective disorder. In 1982 he was treated as an outpatient for severe depression. During the past twenty years he has received sporadic psychotherapy.
The most detailed evidence of his psychiatric problems is contained in the records of his September, 1980 hospital admission and his October, 1981 examination by a consultative examiner, Dr. Benson, hired by the Secretary: When admitted to the hospital in 1980 he was alert and not hallucinatory, but was suicidal with moods rapidly shifting from depressed to anxious. When discharged in November, 1980 he was alert, coherent, non-psychotic, and non-suicidal, but was still depressed and mildly anxious with poor insight and judgment. In October, 1981 Dr. Benson opined that Ostrowski was dreamy but not overly psychotic; that he had had significant psychotic symptoms in the past; that he had a major affect disorder in current remission; that he could perform routine repetitive tasks, follow orders, and respond to normal work pressures. He was not suicidal, hallucinatory, delusional or depressed during that visit.
Ostrowski applied for SSI and SSDI1 benefits in July, 1981. In August and September of 1981 his claims were denied initially, and the denials were affirmed on reconsideration in February, 1982. A de novo hearing before an AU was held in October, 1982, and the AU issued an opinion denying the SSDI claim in February, 1983. The Appeals Council affirmed this denial but remanded the matter to the AU because he had not ruled on Ostrowski’s SSI claim. On December 29, *11131983, the ALJ denied the SSI claim in an opinion mirroring his earlier one. The Appeals Council affirmed. This suit for judicial review followed.2
II.
A person is “disabled” under the Social Security Act if he cannot “engage in any substantial gainful 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)(l)(A)(SSDI). The Secretary uses a five-step inquiry in deciding whether a claimant is disabled. The Seventh Circuit has stripped the process of its regulatory jargon and nuances, summarizing it as follows:
(1) Is the claimant presently unemployed? (2) Is the claimant’s impairment “severe”? (3) Does the impairment meet or exceed one of a list of specific impairments? (4) Is the claimant unable to perform his or her former occupation? (5) Is the claimant unable to perform any other work within the economy? An affirmative answer leads either to the next step or, on steps 3 and 5, to a finding that the claimant is disabled. A negative answer at any point, other than point 3, stops inquiry and leads to a determination that the claimant is not disabled.
Halvorsen v. Heckler, 743 F.2d 1221, 1225 (7th Cir.1984), quoting, Garfield v. Schweiker, 732 F.2d 605, 607 n. 2 (7th Cir.1984); see also 20 C.F.R. § 404.1521 (1984). In reviewing the Secretary’s application of this process, we must uphold her decision as long as her factual findings are supported by substantial evidence and she used the correct legal standards. E.g., Halvorsen, 743 F.2d at 1225. “Substantial evidence” means “such relevant evidence as a ‘reasonable mind accept[s] as adequate to support a conclusion,” considering the record as a whole. E.g., Taylor v. Schweiker, 739 F.2d 1240, 1241 (7th Cir. 1984), quoting, Richardson v. Perales, 402 U.S. 389, 401, 91 S.Ct. 1420, 1427, 28 L.Ed.2d 842 (1971). The “substantial evidence" standard requires the Secretary to base her decision on a careful consideration of all the relevant evidence; she cannot single out those fragments of the record which tend to support her conclusion. Switzer v. Heckler, 742 F.2d 382, 385-86 (7th Cir.1984); Taylor, 739 F.2d at 1243; Garfield, 732 F.2d at 609-10. In reviewing the ALJ’s decision we should consider: (1) the clinical findings of treating and examining physicians; (2) the diagnoses of those physicians; (3) the subjective evidence of pain and disability as testified to by the plaintiff and as observed by others; and (4) the claimant’s educational background, work history, and present age. Whitney v. Schweiker, 695 F.2d 784, 786 (7th Cir.1982). With these basic principles in mind, we turn to the Secretary’s treatment of Ostrowski’s claim.
III.
In evaluating Ostrowski’s claim, the AU considered his back condition and mental condition separately. He determined first that Ostrowski’s back condition was not severe enough to meet or equal the “listed impairments” (“the listings”) of the regulations.3 He thus held that Ostrowski did not pass step 3 of the five-step inquiry *1114outlined above.4 The AU next concluded that “could sit, stand or walk for 6 to 8 hours per day” and thus had the “residual functional capacity” to return to several of his previous jobs, such as medical courier or production controller. As such, Ostrowski had failed to pass step 4 of the inquiry and was denied benefits. The AU next determined that Ostrowski’s emotional illness did not “significantly limit his ability to perform basic work-related functions for any period of 12 consecutive months ...” This amounted to a conclusion that Ostrowski failed to pass step 2 of the inquiry, i.e., his mental impairment was not severe.5 See 20 C.F.R. § 404.1521(a) (1984) (impairment not severe if it does not significantly limit physical or mental abilities to do basic work activities). The Court concludes that neither conclusion of the AU is supported by substantial evidence.
The AU made his most glaring error in analyzing the mental impairment claim. Although acknowledging that Ostrowski has a long history of emotional illness, the AU focussed on two snapshots of that history — the November 1980 report of the discharge from a mental hospital and the October 1981 consultative exam of Dr. Benson — in concluding that Ostrowski’s mental impairment was not severe. In so doing, the AU failed to consider the record as a whole. He makes no mention of and does not consider the evidence of Ostrowski’s ten or so hospitalizations over a period of about 18 years. He also does not address the obvious fact that Ostrowski apparently did not hold down a job for more than a few months at a time. These facts, combined with his testimony, suggest that Ostrowski’s mental impairment is far more severe than acknowledged by the AU. Cf. Halvorsen, 743 F.2d at 1226 (error for AU to not address evidence concerning why claimant lost previous jobs). Given the 18 year history of repeated hospitalizations, we think the AU placed too much weight on the opinion of Dr. Benson, who saw Ostrowski only one day during a period of remission.6 The AU should not have relied on that report without fully considering and evaluating the other evidence of multiple hospitalizations.
The AU’s treatment of the November, 1980 report underscores the selective focus of his inquiry. He first erroneously stated that the report was dated September, 1980. That was the month Ostrowski was admitted to the hospital. The AU does not mention that the November, 1980 report upon which he relies followed two months of hospitalization. The AU did not describe or consider Ostrowski’s condition in September, even though it is detailed in that report. While the report states that Ostrowski was alert and not delusional or suicidal in November when discharged, it *1115also states that he was suicidal, severely-depressed and anxious in September when admitted. The AU focussed only on the half of the report that supported his conclusion, not the whole report, just as he selected only part of the record to base his decision on.
As we noted earlier, the Seventh Circuit has repeatedly held that an AU must consider all of the relevant evidence, including that which counters his ultimate conclusion. E.g., Zalewski v. Heckler, 760 F.2d 160, 166-167 (7th Cir.1985); Garfield, 732 F.2d at 609-10; Zalewski v. Schweiker, 732 F.2d 75, 78-79 (7th Cir.1984). He need not discuss every piece of evidence and testimony; but he “must articulate at some minimal level his analysis of the evidence in cases where considerable evidence is presented to counter the agency’s position.” Garfield, 732 F.2d at 609. On remand the ALJ must consider the reports he relied on in the context of all of the relevant evidence in the record. The ALJ should consider Ostrowski’s claim in the context of two decades of hospitalizations, not in the context of two days of relative lucidity.7 In reviewing the whole record, the ALJ should also consider Ostrowski’s testimony concerning his difficulties dealing with stress in previous jobs, as well as with his family. If he rules against Ostrowski, he should either make a credibility determination or articulate how his testimony weighs in the context of the record as a whole. See Zblewski, 732 F.2d at 78 (AU must explicitly and reasonably reject claimant’s testimony concerning pain if he is to deny benefits); Halvorsen, 732 F.2d at 1226 (AU must articulate grounds for rejecting testimony supporting claimant’s case).
In sum, we hold that the AU’s conclusion that Ostrowski’s mental impairment was not severe is not supported by substantial evidence in the whole record. We express no opinion on the ultimate issues of whether Ostrowski’s impairment is in fact severe, whether it meets or equals the listings of impairments, or, if not, whether he has the residual functional capacity to work. That is for the Secretary to determine as an initial matter on remand after consideration of all relevant evidence and factors described above.
The ALJ made similar errors of omission in assessing Ostrowski’s claim of back impairment. Were the ALJ able to rely only on the medical reports in the record, we would probably uphold his finding of no disability. We need not reach this issue because he again neglected to consider all of the relevant evidence in the record.8 Most significantly, the ALJ did not explicitly evaluate Ostrowski’s considerable testimony concerning his back pain. *1116Ostrowski testified that he regularly feels severe pain in his back, neck, and legs. Sometimes he cannot sit or stand for extended periods in one spot, and needs to lie down. It is clear that his testimony, if credible, suggests that his back ailment would significantly impair his work related functions. In finding that Ostrowski failed to meet the listed impairments, the AU did not explicitly factor Ostrowski’s testimony of pain into his analysis. It could be (although from the record we cannot tell) that Ostrowski’s pain is so severe that he “equals,” if not “meets,” the listings. Under the regulations, a person can be found disabled if his condition substantially equals, rather than precisely meets, the listed impairment. See 20 C.F.R. § 404.-1521(d); § 404.1526 (1984)9 However, the AU did not explicitly evaluate the pain factor, and therefore implicitly decided that Ostrowski's complaints of severe pain were not substantial or credible enough to warrant a finding that he met or equalled the listings. Even if Ostrowski did not equal the listings, the AU’s subsequent finding that he could perform his past jobs because he “could sit, stand or walk” for 6 to 8 hours per day also did not take his corm plaints of pain into account. In reaching his decision, the AU, without explaining why, implicitly rejected or discounted Ostrowski’s testimony, which, if all true, indicated that he could not meet the demands of his previous jobs. As we noted earlier, such gaps in the AU’s analysis warrant reversal and remand of the decision denying benefits. See Taylor, 739 F.2d at 1243-44 (ALJ erroneously ignored claimant’s testimony regarding her limitations); Zblewski, 732 F.2d at 78-79 (AU erroneously ignored claimant’s testimony concerning pain and other symptoms).
Our decision concerning Ostrowski’s complaints of pain is in harmony with the regulations and the new Disability Reform Act of 1984, Pub.L. No. 98-460, 98 Stat. 1794 (enacted October 9, 1984) (“Reform Act”), which created the following standard for evaluating pain:
An individual’s statement as to pain or other symptoms shall not alone be conclusive evidence of disability as defined in this section; there must be medical signs and findings, established by medically acceptable clinical or laboratory diagnostic techniques, which show the existence of a medical impairment that results from anatomical, physiological, or psychological abnormalities which could reasonably be expected to produce the pain or other symptoms alleged and which, when considered with all evidence required to be furnished under the paragraph (including statements of the individual or his physician as to the intensity and persistence of such pain or other symptoms which may reasonably be accepted as consistent with the medical signs and findings), would lead to a conclusion that the individual is under a disability. Objective medical evidence of pain or other symptoms established by medically acceptable clinical or laboratory techniques (for example, deteriorating nerve or muscle tissue) must be considered in reaching a conclusion as to whether the individual is under a disability.
Reform Act, § 3(a)(1) (amending 42 U.S.C. § 423(d)(5)). This standard will be in effect until at least January 1, 1987. Id., § 3(a)(3). This pain standard was intended to codify the Secretary’s existing regulations concerning pain, i.e., 20 C.F.R. §§ 404.1529, 416.929 (1984). See S.Rep. No. 466, 98th Cong., 2d Sess. 24 (1984). It supersedes inconsistent existing case law. See generally S.Rep. No. 466, supra at 23-24; H.R.Rep. No. 618, 98th Cong., 2d Sess. 28-29 (1984), U.S.Code Cong. & Admin.News 1984, pp. 3038, 3065 (Conference Committee Report); 131 Cong.Rec. S11458 *1117(daily ed. Sept. 19, 1984) (remarks of Sen. Long on pain issue).
In this case it is quite likely that Ostrowski’s subjective complaints of pain are grounded, as they must be, in “medical signs and findings ... which show the existence of a medical impairment that results from anatomical ... abnormalities which could reasonably be expected to produce the pain ... alleged.” Reform Act, § 3(a)(1). Ostrowski’s back ailments are well documented, requiring surgery more than once to correct a herniated nucleus pulposa. Several doctors have prescribed drugs for the pain, which suggests that they believe the pain is real and grounded in objective medical evidence. No evidence suggests that any doctor doubted Ostrowski’s reports concerning his pain, either before or after the surgery. The consultative examination by Dr. Bacalla, which occurred well after Ostrowski’s last surgery, revealed that Ostrowski still had degenerative disc disease and osteoarthritis. The upshot of this and other evidence we have not mentioned is that Ostrowski’s pain appears to have a solid basis in objective medical findings. The Reform Act states, the issue of “objective medical evidence of pain ... must be considered in reaching a conclusion as to whether the individual is under a disability.” Id. On remand the AU should determine whether the intensity and persistence of Ostrowski’s pain10 is reasonably consistent with the medical evidence, and if it is, whether the pain in combination with all the other evidence warrants a conclusion that Ostrowski equals the listings or lacks the residual functional capacity to perform his previous jobs or other work in the national economy. The AU improperly failed to factor Ostrowski’s complaints of pain into his findings that Ostrowski is not disabled. The AU must do so on remand, and determine anew whether Ostrowski is disabled.
Although the issue was not mentioned by the parties, we note for purposes of guidance to the AU that he also did not consider whether the combination of Ostrowski’s back and mental impairments rendered him disabled.11 The regulations required the AU to consider the combined effects of “unrelated” impairments if each was “severe” by itself. See § 404.1522 (1984); § 404.1526(a) (1984) (combine to determine if claimant equals listings); § 404.-1545(a) (1984) (combine to determine if claimant lacks residual functional capacity to work). It might be that the AU did not combine Ostrowski’s impairments because he considered them “unrelated” and the mental one not “severe.” Under the Reform Act, the AU must consider the combined effects of unrelated impairments even if each is not “severe” in isolation. See Reform Act, Sec. 4(a)(1).12 That section reflects the common sense notion that a claimant is a whole person with a range of problems, and must be considered as such. Thus, under the new Act Ostrowski should not be split (as he was) into a “back case” and a “psychiatric case” without re*1118gard to the fact that he suffers from both ailments at the same time. In tandem the ailments might render him “disabled” while each one in isolation might not.
Even under the old standard, the AU probably erred in not considering the combined effects of Ostrowski’s impairments because the two are not necessarily “unrelated.” In reviewing Ostrowski’s testimony we noticed that his back condition might exacerbate his mental impairment and vice versa. For example, he testified in more than one place that his bad back is one of the things contributing to his severe depression. Similarly, he apparently uses his back pain to discount the other causes of his depression: a May 26, 1981 report of a psychologist, Dr. Choca, states that throughout Ostrowski’s hospitalization he “kept wanting to see all of his problems as resulting from the back pain.” Indeed, this doctor opined that Ostrowski’s psychological problems in turn exacerbated the extent of his perceived back pain. In sum, there appears to be a feedback between Ostrowski’s two impairments, which the ALT should consider on remand.13
IV.
For the foregoing reasons, the Secretary’s decision to deny Ostrowski disability benefits is not supported by substantial evidence in the record as a whole. We therefore reverse her decision, and remand this case for further proceedings consistent with this opinion. It is so ordered.
