So I am a NHSP student so I have to go into primary care, and I most likely will do FP. I'm ok with this choice, however, I secretly really wish I could do PM&R now that I know more about this field. I know this is a completely hypothetical question but I could help being curious. After FP residency and practicing for atleast 4 years, maybe more. Could I go back and apply for an advanced PGY-2 spot in PM&R?
