The Board dismissed the Veteran's appeals for service connection for right and left lower extremity sciatic nerve problems, as these issues are now considered resolved. The appeal was also remanded to address a broken nose and knee disability claims.

The Board remands the claim for a VA examination to determine if the Veteran's bilateral knee disorders are related to his service-connected disabilities.

The Board denied service connection for a broken nose, deviated septum, low back disability, left foot numbness, right foot numbness, sinus disability, left elbow and forearm disability, left knee disability, and right shoulder strain. Service connection was granted for gastroesophageal reflux disease (GERD) and left hamstring strain. The Board also denied an initial evaluation in excess of 70 percent for posttraumatic stress disorder with residuals of a traumatic brain injury, an initial evaluation in excess of 30 percent for migraine headaches, an initial evaluation in excess of 20 percent for fibromyalgia, and an evaluation in excess of 20 percent for irritable bowel syndrome with diarrhea. The Board denied a total disability rating based on individual unemployability as a result of service-connected disabilities prior to December 1, 2023.

The Veteran's claim for service connection for obstructive sleep apnea (OSA) secondary to his service-connected conditions, with obesity as an intermediate step, is granted.

The Board granted service connection for obstructive sleep apnea, effective from the date of the February 2025 rating decision.
