Help with VA benefits?

I'm in the Army and I’ve been diagnosed with Degenerative joint disease of the Spine and herniated disc of my C-5 and C-6 vertebra and given a P-2 profile where I can’t run or do pushups. I’ve been in 5 years and ETS next year so I’ll have served six. I hurt my neck doing crew drills during my second year but never went to the doctor. Then one morning I woke up and had horrible pain and couldn’t move.Does anyone know a ballpark figure or % of what my VA benefits will be? My doctor said I’ll defiantly get something but doesn’t know what. Has anyone had anything similar?
