Claimant Florence Edwards appeals a district court order affirming a decision of the Secretary of Health and Human Services that denies social security disability benefits. We affirm.

The background facts are thoroughly detailed in the decisions below. Briefly, claimant alleges a disability due to injuries she sustained on February 28, 1988, when she jumped from a second story window to escape a fire. She suffered significant fractures to both feet and a fractured vertebrae. After a month in the hospital and physical therapy on an outpatient basis, she returned to her work at a shoe company in September, 1988. Adjustments were made in her work duties to accommodate her new mobility limitations, and she remained at her job until the plant closed in December, 1988. For a period thereafter she accepted unemployment benefits. In April, 1989 she underwent a subtalor fusion of the left foot. At the time the treating orthopedist noted that as a result of her fractures her feet were significantly deformed, with residual arthritis. In July, 1990, a similar subtalor fusion was performed on her right foot. It is not disputed that claimant relies on a cane, walks with difficulty, and apparently suffers permanent limitations on her ambulatory abilities. She also suffers from hypertension and obesity, and complains of chronic lower back pain.

There were two hearings before an Administrative Law Judge (ALJ) on claimant's application for disability benefits. Claimant was represented by the same counsel at both hearings. A decision denying benefits after the first hearing was vacated by the Appeals Council, and the matter remanded to the ALJ for the taking of additional evidence relating to claimant's post- operative condition. The second hearing also resulted in a decision to deny benefits, and the Appeals Council denied review. On cross-motions by the parties, the district court affirmed the Secretary's decision in a lengthy memorandum opinion.

The ALJ's second decision found claimant not disabled at step five of the familiar sequential analytic process, in that claimant had a residual functional capacity to perform a limited range of unskilled sedentary jobs which exist in significant numbers in the national economy. 20 C.F.R. Secs. 404.1520(f), 404.1561, 404.1566. Claimant renews in this court several of the multiple assignments of error she urged below, and attempts to add a new one for the first time on appeal. First claimant argues, as below, that the ALJ failed to develop an adequate record relating to her residual functional capacity, because he violated an "explicit order from the Appeals Council to have the examining physician [Dr. Shea] complete a specific form ... " According to claimant, Dr. Shea should have filled out the very same preprinted form that was used by claimant's treating doctor, Dr. Wachs.

Claimant's reading of the Appeals Council's order is questionable,1 but we need not tarry over this detail because the record developed below is clearly adequate. The ALJ had before him a thorough residual functional assessment from Dr. Wachs, who was associated with claimant's treating orthopedist. In addition, there was a full consultative examination by Dr. Shea, who was also familiar with the claimant, having evaluated her in connection with previous applications. Dr. Shea's report contains detailed assessments of appellant's range of motion, reflexes, flexion, walking, sitting, and standing abilities. Both doctors reported substantial limitations on claimant's functional abilities, reducing the range of work which she might perform to less than the full range of sedentary jobs available.

It is true that the two doctors' reports are in different formats, but we fail to see any prejudice in this asymmetry. Each report formed the basis of a separate hypothetical question propounded to the vocational expert (VE). The VE identified approximately 67,500 jobs in the national economy which claimant might perform despite the functional limitations reported by Dr. Wachs, and 135,000 jobs despite the limitations observed by Dr. Shea.2 Even the lower of these two estimates sufficed to satisfy the Secretary's burden of showing "significant numbers" of suitable jobs in the national economy. 20 C.F.R. Sec. 404.1566; see also Keating v. Secretary of HHS, 848 F.2d 271, 276 (1st Cir. 1988) (to show that work exists in significant numbers, the Secretary must show significant, not isolated, numbers of jobs which a claimant can perform).3

Since the ALJ's conclusion finds substantial support in the treating doctor's, Dr. Wach's, assessment, claimant's fallback argument that the ALJ substituted his own opinion for that of Dr. Shea is irrelevant, and in any event, rests on a strained reading of the record. It is clear that claimant suffered no prejudice from the format of Dr. Shea's report.

Second, claimant argues that the ALJ did not properly evaluate her subjective complaints of pain. On our own review, we agree with the district court that the ALJ gave full and careful consideration to claimant's pain complaints in conformity with the regulations and case law. See Avery v. Secretary of HHS, 797 F.2d 19, 21 (1st Cir. 1986). The record does not support the contention that the ALJ gave undue weight to claimant's use of non-prescription pain medications. We defer to the ALJ's assessment of claimant's credibility, especially as it was supported by specific findings. See Frustaglia v. Secretary of HHS, 829 F.2d 192, 195 (1st Cir. 1987).

Third, claimant argues, for the first time on appeal, that there was insufficient evidence because the VE "mischaracterized," as exertionally sedentary, the various jobs he identified as available to a person with claimant's characteristics. The VE testified that "some" jobs in the following categories would be suitable: machine operation jobs, such as grinding, buffing and polishing; manual assembler; inspector; and cashier/ticket seller.

In her appellate brief, claimant assigns code numbers to these job titles based on information in the Dictionary of Occupational Titles (revised 4th ed. 1991) (DOT). All of the code numbers which claimant assigns correspond to jobs which the DOT classifies as requiring a greater than "sedentary" exertional capacity, and in one instance, a greater skill level than claimant possesses.4

The VE, however, did not assign DOT code numbers in his testimony, only general job titles. While the code numbers affixed by claimant refer to similar job titles, there are numerous DOT listings with superficially similar titles, or work descriptions, some of which are classified as sedentary and unskilled.5 Claimant's point thus cannot be readily verified by simply comparing some DOT listings with the VE's testimony.

In other circumstances, the uncertainty generated by claimant's observations might cause concern. While not the only reliable source of job information, the Secretary takes administrative notice of the accuracy of the DOT's generalized job descriptions. See 20 C.F.R. Sec. 404.1566(d), Subpart P, app. 2, Sec. 200.00(b). The Secretary bears the burden of proving the existence of jobs in the economy that the claimant can perform. See Goodermote v. Secretary of HHS, 690 F.2d 5, 7 (1st Cir. 1982). A clear dichotomy between the DOT and the VE's testimony on this point may call into question the sufficiency of the Secretary's evidence.

Courts have vacated the Secretary's decisions where the VE's testimony is contradicted in its entirety by the DOT and the only reasonable explanation seems to be that the VE made a mistake. See, e.g., Young v. Secretary of HHS, 957 F.2d 386, 392 (7th Cir. 1992) (VE's testimony as to characteristics of claimant's former jobs inconsistent with DOT description); Ellison v. Sullivan, 921 F.2d 816, 821-22 (8th Cir. 1990) (claimant limited to sedentary work, all jobs listed by VE rated as light to heavy); Tom v. Heckler, 779 F.2d 1250, 1255- 56, 1257 n.12 (7th Cir. 1985) (claimant limited to sedentary work; all jobs listed by VE rated as light); Mimms v. Heckler, 750 F.2d 180, 186 (2d Cir. 1984) (same). In at least one of the cases, Tom, the court treated an irreconcilable conflict as the equivalent of plain error, remanding despite the failure of the claimant to object below.

Here, however, not only is the alleged DOT contradiction uncertain, but the circumstances surrounding claimant's failure to object at the hearing suggest that this uncertainty is better explained by hindsight interpretation than by actual error. Claimant was represented at the hearing by an experienced attorney, who evinced no surprise or confusion at the VE's testimony. On the contrary, he complimented the VE on the thoroughness of his presentation. The attorney was keenly aware that a discrepancy between the VE's articulation and the DOT might be used to claimant's advantage, as shown by a specific objection he made minutes before to another VE's opinion in the same case. A copy of the DOT was apparently available in the hearing room, for the transcript shows that the VE directly consulted the DOT at an earlier point in his testimony. Nevertheless, claimant's attorney did not request specific DOT code numbers, nor seek any other information that might shed light on the VE's sources. The first allusion to this allegedly striking VE error appears in a one-sentence paragraph inserted into claimant's motion for reconsideration of the district court's decision.

"We have long recognized that social security cases are not strictly adversarial." Evangelista v. Secretary of HHS, 826 F.2d 136, 142 (1st Cir. 1987). Here, however, we see no good excuse for the failure to raise this matter sooner, and claimant offers none. In these circumstances, there is no unfairness in applying the "ordinary rule that appellate courts will not consider issues not raised below." Gonzalez-Ayala v. Secretary of HHS, 807 F.2d 255, 256 (1st Cir. 1986) (citations omitted); see also Torres v. Secretary of HHS, 870 F.2d 742 (1st Cir. 1989) (claimant's argument that ALJ's hypothetical omitted a crucial fact will not be entertained for first time on appeal where issues were simple, it was not likely that VE failed to consider the omitted fact, and claimant could have posed his own hypothetical); cf. Evangelista, 826 F.2d at 142- 43 (where claimant was able to fairly present his case and the ALJ's decision was based on substantial evidence, appeals court will not remand for presentation by claimant of arguably "new and material evidence" in absence of "good cause" adequate to excuse the failure to offer the evidence sooner).

Accordingly, the judgment below is affirmed.
