can a NP work in phys med & rehab? whats the best route for me?

im a student that has been accepted to med school, but chosen not to good afterall. originally i wanted to do physical med & rehab as a physiatrist. but since ive decided as a nontrad student that that would be way too long training, im looking into nursing school.

i have all the pre-req's for medicine. but now i would like to convert my non-sci., bachelors degree to a bsn first, i assume? then continue for at least 2-3 yrs more to get a cert. fam NP certificate? if anyone knows how this is done or if this is a do-able goal, please send me a message or reply here. thanks.
