Entitlement to service connection for a peripheral nerve disorder of the left lower extremity is remanded.

Board reasoning

The Board found that the record before it was insufficient to decide the claim and that additional development was necessary to correct a pre-decisional duty to assist error. In particular, it identified the need to obtain private treatment records via VistA Imaging, to secure SSA records (including application and decision), and to schedule a new examination with a qualified examiner to determine onset and etiology of any left lower extremity peripheral nerve disorder, including potential relationship to service or to a service-connected disability. The Board explained that the May 2021 examiner's rationale was inadequate and relied on the absence of records in service, citing Buchanan v. Nicholson as guidance, and emphasized the Veteran's competent reports of symptoms which required corroboration through a proper medical opinion.
