The Veteran's migraines are granted a 30 percent rating from May 6, 2014 to September 2, 2015. Service connection for low back disability and peripheral neuropathy of the lower extremities is remanded.

The Veteran was granted a 70 percent initial disability rating for PTSD effective December 2, 2021, but the claim for an increased rating in excess of 70 percent was denied. The appeal also included claims for service connection and ratings for various conditions, some of which were granted while others were remanded.

The Board remands the claims for service connection for various disabilities to the AOJ for further development and consideration of evidence not previously considered.

The Board denied service connection for the veteran's claimed conditions, including right shoulder arthritis, left shoulder arthritis, right hip condition, left hip condition, low back disability, and bilateral lower extremity radiculopathy, as there was no evidence of in-service injury or illness related to these conditions.

The Board denied the Veteran's appeal for an initial rating in excess of 30 percent for migraines, finding that his symptoms more closely approximate a 30 percent disability rating.
