Sir, I think there may be some confusion. The law on effective dates of benefits is clear and can be found at 38 US Code 5110. You can see that law herehttp://www.law.cornell.edu/uscode/text/38/5110
There are exceptions to this rule...but none that meet the criteria that you state.
If you look at the law, it states
(a) Unless specifically provided otherwise in this chapter, the effective date of an award based on an original claim, a claim reopened after final adjudication, or a claim for increase, of compensation, dependency and indemnity compensation, or pension, shall be fixed in accordance with the facts found, but shall not be earlier than the date of receipt of application therefor.
THe key is the last clause
but shall not be earlier than the date of receipt of application therefor.
If you did not apply until 2011, that is the effective date.
I am very sorry to have to bear bad news...I do not know what literature you are referring to when you say
It is my understanding from some VA literature that if a veteran can show a diagnosis and continued treatment before the application for disability that the effective date can I be moved back to the original diagnosis and treatment date.
But any literature that says this is flat out wrong...Title 38 of the US Code is the law that applies. It was established by Congress...the VA is required to follow that law. So it is not possible to gain an effective date prior to the date you have filed.
