Secondary service connection is governed by 38 CFR 3.310, which allows a condition to be granted if it is either caused or aggravated by an already service-connected disability. Because tinnitus is one of the most commonly service-connected conditions, it is not unusual for veterans to pursue migraines as secondary to it, arguing that the constant ringing, sleep disruption, or associated stress triggers or worsens headache activity.
To succeed on a secondary claim, the record generally needs three things: (1) a current diagnosis of migraines, typically documented through treatment records or a Disability Benefits Questionnaire (DBQ) for headaches; (2) confirmation that tinnitus is already service-connected; and (3) a medical nexus opinion connecting the two, stated in terms of "at least as likely as not" (the 50 percent or greater standard VA uses). A private nexus letter from a physician or audiologist that explains the physiological or clinical pathway—such as sleep deprivation from nighttime tinnitus leading to migraine onset—can carry significant weight, especially if it cites supporting literature or the veteran's specific treatment history rather than offering only a conclusory statement.

VA raters weigh the nexus letter alongside these statements and the existing medical record as a whole.
If a migraine claim was previously denied for lack of nexus, filing a Supplemental Claim (VA Form 20-0995) with the new nexus letter and lay statements as new and relevant evidence is generally the appropriate path, since it allows VA to weigh the new medical opinion without needing a full appeal. Alternatively, a Higher-Level Review or Board appeal (VA Form 20-0996 or 10182) may be options if the veteran believes the prior denial contained a clear error rather than simply lacking evidence.
Outcomes in these secondary-connection cases vary considerably depending on how well the nexus letter addresses causation versus aggravation and how consistent the treatment record is with the claimed pattern. The concrete next step is to file a Supplemental Claim with the new nexus letter, personal and buddy statements, and any updated treatment records showing the migraine-tinnitus correlation.
