As the title says, I completed my residency in the US, became board certified, and have been practicing for a bit. I am well trained and well-rounded - not just in terms of my field. Now, I am looking to retrain in another field for personal reasons. Has anyone else been in this position and/or know what my options are? Can I even apply through the NRMP match? Is there any possibility of getting any credit for my initial residency rotations? I realize that it is a huge decision and it is not one that I have taken lightly. But, this is what I need to do in order to have professional satisfaction in the long-term.
