I would definitely wait till the court case is over to not complicate things.
Definitely get a lawyer.
Oregon is a pretty liberal state if you get the right people on the jury this could go your way very easily.I doubt the judge will allow your med license in after the fact but if you have a good attorney he'll find a way to sneak something in.
All it takes is 1 person to not convict and your off.Make sure you discuss this with your attorney.
