I was put on TDRL at 40% in 2001, and in 2006 was given a 20% rating and given severance. I went through going to Navy Yard to the PEB why I thought it was wrong, was denied and taken off TDRL. I was put on TDRL for back surgeries (3 while in service) and while on TDRL, I had titanium installed with a spinal fusion. How can that be done and still reduce me from 40% to 20%? Is there a way to get reevaluated or get my retirement status back?
