Whoever is saying that, they are ignorant. So long as your conditions are in the line of duty and unfitting, you are due compensation.
Based on what you wrote, should be unfitting and rated at a minimum of 50% with placement on the TDRL.
Hard to say for sure, but likely, 10-20% rating if unfitting.
This is a harder issue, because the VA did not find a diagnosis. Highly complicated issue based on the facts of your case. I suspect you should be rated 10-20% based on this. However, you may well have to appeal/fight this issue out.
Thanks Jason. The shin splints isn't that big of a deal. That was added right before my NARSUM. My MEB doc said she felt she should add it. I let her do what she had to do. I talked to my PEBLO she said it would be another month or 2 before I would see a unfit memo!
