They decreased my rating 30-0 for migraines and headaches.

Tell me how I went to my two c&p exams and told them I have frequent headaches and migraines that impact my daily life. I have to get Botox for God sakes and they gave me a damn 0 percentage rating? I knew the VA rater would screw me. My PTSD/MH/TBI got deferred. I guess I have to contact my local VES for a higher level review. Are these c&p examiners doing their job or what? Why am I seeing so many of us getting reduced when we have medical evidence from active duty and current VA care.
