If I read this correctly, you were receiving TDIU, from 2009, and went back to work in 2011 (while still collecting TDIU?), I'd be worried about working and collecting TDIU. If that's what happened, I'd be concerned the VA would find out and declare a fraud, take away all your bennies, put you in jail and have you pay them back. If that's the case, "I'd" contact the VA and voluntarily get it corrected, NOW, before something happens. I hope for your sake I misread this post. Please correct or ignore me if that's the case.
P&T can be taken away at anytime. I doubt they'll reduce the 100% or the P&T but I'd worry about the "fraud" of collecting TDIU and working. They love to prosecute and make examples of vets who they consider abuse the system. If they do that they could stop all benefits, due to the fraud. Sorry I cant offer anything more positive. jmo
I'd contact a criminal defense attorney ASAP.
