If your med school offers it and it's either T1 or T2 do it. I'm in a similar boat I'm in a dual admit med program, I wish my school offered combined JD programs. Go for it but also do your residency.
I'm in a BS/DO program going to do UG. Take a leave of absence, do an accelerated JD probably at the University of Kansas (2 year program). Grab my DO, do a residency in ophtho or ortho. Then I may do health law as an attorney doing chart reviews/malpractice defense.
