The Board granted service connection for right lower extremity peripheral neuropathy but denied service connection for RLE peripheral arterial disease and peripheral vascular disease.

The Board remands the claim for service connection for peripheral vascular disease to ensure that the RO substantially complies with its previous remand directives.

The Board granted an earlier effective date of October 2, 2015 for the grant of service connection for lumbar sprain and right lower extremity peripheral neuropathy due to good cause shown for the Veteran's failure to file a Notice of Disagreement within one year of the initial denial.

The Board remands the claims for further development, including obtaining medical opinions to address the nature and etiology of the claimed conditions and their relationship to service-connected disabilities.

The Board remands the claims for a higher rating in excess of 20 percent for lumbar, status post partial laminectomy and discectomy, an initial higher rating in excess of 20 percent for left lower extremity (LLE) peripheral neuropathy, an initial higher rating in excess of 20 percent for right lower extremity (RLE) peripheral neuropathy, and an initial compensable rating for lumbar scar due to deficiencies in the VA examinations.
