Danny Depover applied for disability insurance benefits based on a back injury and related surgery, visual limitations, and high blood pressure. The Social Security Administration denied his application initially and on reconsideration. After holding a hearing, an administrative law judge (ALJ) determined that Mr. Depover was not disabled, and the Social Security Appeals Council denied his request for review. The district court 1 upheld thе administrative decision, and Mr. Depover appealed to this court. We affirm.
On appeal, Mr. Depover contends that the ALJ did not adequately support his finding that Mr. Depover’s complaints of back pain were “not fully credible,” failed to make sufficient findings regarding his residual functional capacity (RFC), and submitted an inadequate hypothetical question to a vocational expert. We review the district court’s decision to uphold the denial of social security benefits
de novo. See Pettit v. Apfel,
I.
The ALJ must follow a five-step process to determine whether a claimant is disabled.
See
20 C.F.R. § 404.1520;
see also Bowen v. Yuckert,
To reach his decision, the ALJ was required to assess Mr. Depover’s RFC,
see
20 C.F.R. § 404.1520(e), which is defined as “the most [a claimant] can still do despite” his or her “physical or mental limitations,”
see
20 C.F.R. § 404.1545(a). The RFC “is a function-by-function assessment based upon all of the relevant evidence of an individual’s ability to do work-related activities.” S.S.R. 96-8p,
In
Polaski v. Heckler,
Mr. Depover challenges the ALJ’s finding that he did not request pain medication until December, 1999, and then did so not for back pain but because of a mass in his leg. The failure to request pain mediсation is an appropriate consideration when assessing the credibility of a claimant’s complaints of pain.
See Haynes v. Shalala,
In April, 1998, Mr. Depover’s surgeon reported that he did not take any pain medication, and the next month the doctor stated that Mr. Depover “tаkes no routine medications.” About a year later Mr. Depover returned to the surgeon, and his notes again reflect that the claimant “takes no pain medication.” The next month when Mr. Depover аpplied for social security disability benefits, he answered “no” when asked on a form whether he was taking any medications for his injury. Having reviewed the entire record, we believe that the ALJ could have reasonably concluded that after his November, 1997, back surgery Mr. Depover did not seek pain medication until December, 1999, when he had pain caused by a mass in his leg. We also think that it was reasonable fоr the ALJ to consider the fact that no medical records during this time period mention Mr. Depover having side effects from any medication.
Mr. Depover worked for Swiss Colony filling orders in its warehouse for sevеral months in 1998, and the ALJ characterized this work as “substantial gainful activity” during his period of alleged disability that was inconsistent with his subjective complaints. Mr. Depover, however, relies on 20 C.F.R. § 404.1574(c)(3), to argue that the emрloyment should have been considered “an unsuccessful work attempt” because it lasted less than three months and he “stopped working ... because of [his] impairment,” id. Although the job lasted only three months, or so, we nevertheless find that there was substantial evidence to support the ALJ’s finding that Mr. Depover left that job not because of his disability, but because the work was seasonal and the season ended. Fоr example, on a social security form dated June, 1999, Mr. Depover himself stated that he worked for Swiss Colony from October, 1998, until December, 1998, or January, 1999, five days a week, eight hours per day, and the job endеd because it was “seasonal work.” Since the evidence supports a finding that Mr. Depover left because the job ended, we believe that it was not unreasonable for the ALJ to find that this work “suggests that his impairments are not as severe as alleged.”
Finally, the ALJ relied on the medical opinions and notes in the record to support his conclusion that Mr. Depover’s pain, although present to somе degree, did *567 not prevent him from working. As the ALJ found, “[n]one of the physicians involved in [Mr. Depover’s] treatment have offered an opinion that the claimant is disabled or made any statement or recommendation that he would be unable to work at a substantial gainful level.” With respect to his back injury, his surgeon released him to return to a light duty job with no lifting over forty pounds, no repeated lifting over thirty pounds, and no repeated bending. Having carefully reviewed the record and the ALJ’s decision, we reject Mr. Depover’s contention that the ALJ did not properly analyze the credibility of his subjective complaints.
II.
Mr. Deрover also argues that the ALJ erred in failing to make a finding as to his residual capacity to sit, stand, and walk. The ALJ made the following findings regarding Mr. Depover’s RFC:
The medical evidence shows that the claimant is сapable of lifting and carrying 40 pounds occasionally and 20 to 30 pounds frequently; he cannot repetitively bend, stoop, squat, kneel, or crawl and he cannot continuously climb; he must avoid work around moving machinery and heights; and he cannot perform work requiring full peripheral vision or depth perception.
As Mr. Depover notes, the RFC should “identify the individual’s functional limitations or restrictions and assess his оr her work-related abilities on a function-by-function basis, including the functions in ... 20 C.F.R. § 404.1545[ (b) ],” which include “sitting, standing, [and] walking.”
See
S.S.R. 96-8p,
Here, however, the ALJ did not simply describe the RFC in “general terms.” He made explicit findings and, although we would have prеferred that he had made specific findings as to sitting, standing, and walking, we do not believe that he overlooked those functions. We think instead that the record reflects that the ALJ implicitly found that Mr. Depover wаs not limited in these areas: We note initially that all of the functions that the ALJ specifically addressed in the RFC were those in which he found a limitation, thus giving us some reason to believe that those functions that he оmitted were those that were not limited. Furthermore, at the hearing, the ALJ first posed a hypothetical question to the vocational expert that included the RFC that he (the ALJ) found. After the expert concluded that Mr. Depover could perform his past relevant work as a sporting goods sales clerk or a cashier/checker, the ALJ asked him an alternative hypothetical question that included the limitations on sitting, standing, and walking to which Mr. Depover had testified at the hearing. We note, also, that in his decision the ALJ noted that Mr. Depover had testified that he could not do his past work because he could not stand for long periods. Therefore it appears to us that the ALJ did not simply overlook the possibility that Mr. Depover was limited with respect to sitting, standing, or walking when he stated his RFC. Having carefully reviewed the record, we believe that the ALJ implicitly found that Mr. Depover was not limited in these functions, *568 and in this instance we do not see any reason to remand to make the findings explicit.
III.
In his final point, Mr. Depover сontends that the ALJ was required to refer to his capacity to sit, stand, and walk in the first hypothetical question that was posed to the vocational expert. But, as we have said, the ALJ implicitly found that Mr. Deрover was not limited as to those functions, and therefore we think that the hypothetical question was complete without a reference to them. The expert’s response to the hypothetiсal question, as properly posed, supplied substantial evidence to support the ALJ’s finding that Mr. Depover could return to his past relevant work as a sporting goods sales clerk or a cashier/checker.

Accordingly, we affirm the judgment of the district court.
