← All secondary claims · Ratings by condition
A secondary claim is a condition caused or worsened by one the VA has already service-connected. The causation fight is already half-won — the VA agreed your tinnitus came from service; the question is only whether it caused the migraines. That's a medical question with a recognized answer.
The connection
Constant ringing is not a background nuisance — it is a neurological stressor that disrupts sleep and raises baseline arousal, both established migraine triggers, and the two conditions share overlapping neural pathways in the current research. For a veteran with service-connected tinnitus who later develops migraines, this is a recognized secondary theory worth developing properly.
How the VA rates migraines
50% = very frequent completely prostrating and prolonged attacks productive of SEVERE ECONOMIC INADAPTABILITY · 30% = characteristic prostrating attacks ~once a month over the last several months · 10% = less frequent.

What the claim needs — the three legs
- The anchor: service connection for the tinnitus (see how that condition is rated). Not connected yet? File it first — a secondary claim needs something to attach to.
- A current diagnosis of migraines — the VA rates diagnosed conditions, not symptoms.
- The medical link. An opinion stating it is "at least as likely as not" that the tinnitus caused or aggravated the migraines. The VA's own C&P examiner supplies this free in most cases; your own doctor can too. A paid independent opinion is the last resort, not the first move.
