Concerning your pilot license, you certainly should have received a response from the FAA when your attorney disclosed the infraction. I would not have left that in the hands of my attorney. The fact that you didn't receive a response is reason for some concern. Are you sure the right people were properly notified?
Concerning your medical, your AME can issue your certificate with a single DUI in which you performed the BAC test and the results were below .15, as citation35hf pointed out.
