Hello! I know you posted this last year, but I also noticed that the available answers are few.
I would love to hear that your migraines are under control, however, that is a very rare accomplishment.
I have had migraines since 1971, at 11yr of age. My mother, her father, and his father also had them. My migraines like you are daily and have been very difficult to control.
About obtaining Disability for them. I was placed on 100% Disability status in 2004. I too, was denied the first time, but after hiring a contingency lawyer, it was approved immediately. At that time, the hearing judge informed me that Migraines were not on the list of approved diagnosis but based on my records it was being approved and would be reviewed in 5yrs.
When the 5yrs arrived, I got a letter saying that no additional info was required and that my coverage would continue.
Since then, I have talked to several people, one of them my cousin, that have been approved based on a diagnosis of migraines.
If you are still suffering from daily migraines and have not been able to find a treatment to stabilize them, and are still NOT approved for Disability. I would definitely talk to a lawyer that will take you on a contingency suit.
You didn't include a state, but I'm in Arkansas. I sincerely hopes this helps.
