Questions on Med board

I am currently on active duty in the Army at Ft Bragg NC assigned to 82nd Airborne Division. I recently how Anterior Spinal Decompression of two levels c5-c6 and c6-c7, with placement of bone grafts and a plate with 6 screws. There is also mild left foraminal stenosis at level 4-5 which might need work at a later time. I am currently still under the care of a civilian Doctor and Con leave until Feb. I am very confused to what takes place next. I have questions if someone could possibly help. I want to gain all the information I can before going back to work.

1. How does the Med Board process start? is it my responsiblity or do I have the civilian write a letter or will the Army just do it?

2. I have 10 Years active and 7 reserve. Will I be medicaly retired so as to not lose all the time I have served?

3. I am not sure where I recieved the injury could have been from explosion in Iraq or a jumping or grappling training. Does it matter?
