If nothing has actually changed with your health since your previous medical, it's still good (you'll have to report the VA rating and specific conditions on your next medical).
But if it's is all long-term stuff, you *should* have already reported it to the FAA on past medicals anyway. You could be in legal jeopardy if there's anything significant buried in your mil records which the VA dug up and granted a rating for. Most especially anything like mental health/PTSD/TBI.
FAA medical is not like the mil "what they don't know can't hurt them". What the FAA doesn't know can send you to jail, if it's documented somewhere else. Pilots have gone to federal prison recently for getting disability but not reporting it to the FAA. Yes they can and sometimes do cross-check other federal records. Yes there's a loophole around HIPAA.
As JB said, it's OK to possess a medical with DQ conditions as long as you don't actually exercise the privilege. It is never OK to lie or omit info on the FAA form (read the fine print, I think it's five years at club fed).
If you got ratings for conditions which you knew you had all along but had not reported to the FAA, that's a potential can of worms. Might want to talk to a lawyer, especially if any of the conditions are potentially disqualifying.
