Your question is not clear as to what legal advice you need concerning the VA and what on your discharge you want changed. If you were honorably discharged from the USAF after your term of service expired you are generally eligible for VA medical benefits. You are also most likely eligible for VA disability benefits but you will need to submit a claim for them if you have not done so already.
I have handled several of these cases. Without seeing your records it is hard to say upon what they based their diagnosis, but the BLUF is that the only way to get the record changed is to prove it is wrong. The only way to prove it is wrong is either by a review of the medical records or by an independent diagnosis. If you would like to discuss further, please give me a call.

There should not be a problem getting VA Medical assistance - if your condition is service connected or aggravated. You're message does not say how long you were serving before discharge. If your condition was service connected or aggravated - you may be eligible for VA disability compensation as well. Regarding your DD214 - you can petition the AFDRB or AFBCMR to get changes made to your DD214. You can contact my office for a free consult.
