The Board denied the veteran's claims for service connection for fecal incontinence, post anal fissure repair, with recurrent hemorrhoids; a low back disorder (claimed as low back pain); and leg problems secondary to the claimed low back disorder due to lack of evidence showing current disabilities or a nexus between the claimed conditions and active military service.

The Veteran was granted earlier effective dates for service connection of left lower extremity radiculopathy, sciatic nerve; right lower extremity radiculopathy, femoral nerve; and fecal incontinence, all from May 7, 2012. An increased rating of 20 percent for right lower extremity radiculopathy, sciatic nerve, was also granted effective November 30, 2018.

The Board remands the claims for service connection for flat feet, irritable bowel syndrome, duodenal gastritis, and fecal incontinence to correct pre-decisional duty to assist errors.

The Board granted service connection for fecal incontinence as secondary to the Veteran's colon cancer residuals and denied a TDIU prior to April 21, 2024 and a higher rating for heart disability prior to that date. The claim for a higher rating for colon cancer residuals was remanded.

The Board denied an earlier effective date for service connection of hypertension and remanded several other claims, including those for brain damage, memory loss, vertigo, seizures, acquired psychiatric disability, urinary incontinence, and fecal incontinence.
