Brainstem Compression

I was diagnosed with migraines, meniere’s and MAV 3 years ago. I had an MRI that shows one of my vertebral arteries is causing brainstem and spinal compression. Apparantly its congenital and I was just born this way. I have asked my neurologist and ENT if this could be the cause of all of my symptoms. They both seem to think that because it’s always been this way that it has nothing to do with my problems. I have tried to research the subject but I’m not really coming up with much. I was wondering if anyone else out there has had similar MRI results.
