OK I retired on December 31 2014 and started receiving retired pay. July 2017 applied for VA disability for knee and tiniest with no hearing loss 30% plus 10% awarded April 2018. They deducted my VA pay from my retirement pay. May 2017 filed CRSC for 30% for knee as it occurred during training for deployment. They denied the knee but awarded 10% for hearing even though I didn’t apply for that. I submitted over 20 pages of medical and investigation reports of the knee injury all showing it occurred during training for war. My question is how far back with they pay me the 10% and does it not affect my current VA and retirement pay?
