VA Headache Claim Denied

My headache claim was denied. I had headaches prior to service but they turned into migraines while I was in and I still suffer with them monthly. My supplemental claim came back and it was denied. Best part is it says 

 

“I have been diagnosed with a disability. VA examinations on the dates confirm diagnosis of migraines” what do I do here? Refile with a claim for migraines?
