The Board remands the claim for a new VA examination to assess the nature and etiology of the Veteran's migraines, specifically whether they are caused or aggravated by his service-connected tinnitus.

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 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.

The Board remands the claim for service connection for migraines, including as secondary to cervical strain, due to pre-decisional duty to assist errors in not translating relevant Spanish documents and ensuring a VA examiner considered all evidence.

The Board granted a restoration of the separate 10 percent rating for vertigo, an earlier effective date for service connection for vertigo and migraines, and a 30 percent rating for hypothyroidism with heart murmur. The decision also denied an earlier effective date for hypertension and remanded claims for obesity, obstructive sleep apnea, and individual unemployability.
