United States District Court, M.D. Pennsylvania
ROSE M. SINKER, Plaintiff,
CAROLYN W. COLVIN, ACTING COMMISSIONER OF SOCIAL SECURITY, Defendant.
CHRISTOPHER C. CONNER, Chief District Judge.
Plaintiff Rose M. Sinker has filed this action seeking review of a decision of the Commissioner of Social Security ("Commissioner") denying Sinker's claim for social security disability insurance benefits.
Disability insurance benefits are paid to an individual if that individual is disabled and "insured." Sinker met the insured status requirements of the Social Security Act through December 31, 2009. Tr. 23. Thus, Sinker must establish that she suffered from a disability on or before that date. 42 U.S.C. § 423(a)(1)(A).
Sinker protectively filed her application for disability insurance benefits on April 6, 2011, alleging that she became disabled on April 24, 2004. Tr. 21, 116. By operation of the doctrine of res judicata , Sinker's period of disability was limited to February 8, 2008. Tr. 22, 23. Sinker has been diagnosed with several disorders, including: degenerative disc disease of the lumbar spine, degenerative disc disease of the cervical spine, fibromyalgia, chronic obstructive pulmonary disease, hypertension, carpal tunnel syndrome, and hyperlipidemia. Tr. 23-24, 510. On May 26, 2011, Sinker's application was initially denied by the Bureau of Disability Determination. Tr. 95.
A hearing was conducted by an administrative law judge ("ALJ") on March 23, 2012, where Sinker was represented by counsel. Tr. 38-71. On June 25, 2012, the ALJ issued a decision denying Sinker's application. Tr. 21-30. On July 30, 2013, the Appeals Council declined to grant review. Tr. 1. Sinker filed a complaint before this Court on September 5, 2013, and this case became ripe for disposition on March 31, 2014, when Sinker filed a reply brief.
Sinker appeals the ALJ's determination on two grounds: (1) the ALJ erred in discounting Sinker's credibility, and (2) the ALJ erred in finding at Step Five that Sinker was not disabled. For the reasons set forth below, the case is remanded to the Commissioner for further proceedings.

Sinker was forty-eight years of age at the time the ALJ rendered his decision; she has a tenth grade education and is able to read, write, speak and understand the English language. Tr. 42, 130, 132.
