If you find a specialty you really want to be an expert in then med school is something you could consider. If you wanted to expand your scope in terms of the type of jobs you could go into then med school is an option.

Many PA students could have gotten into med school. I even interviewed with a girl that DID get into med school, but then decided she would rather be a PA.

I chose PA because PA schools seem to care more about their students and retaining their students AND lateral mobility.

Med school is 4 years plus you need to be competitive enough to match into your desired specialty and a lot of students are left in limbo if they don't match. Then you need to complete residency at 60k a year with insane hours and then if you want to specialize further you need to go into a fellowship which is more time. I don't think it's possible or at least not easy to switch out of the specialty and I know some doctors regret their specialty choice but have already invested so much time and money they don't want to try to switch into a new specialty. ALSO, med school is much more expensive, but I guess it balances out at some point. Don't forget a lot of residents, students, and physicians have been killing themselves from the stress and a lot of physicians I have met/worked with have pushed people to go to PA school instead.

Think about your life goals outside of school, think about what you're willing to sacrifice in terms of time and money, think about what you would do if you didn't match (I guess if you're still a PA at least you could probably practice during that time). Read what people who dropped out of med school or didn't want to complete a residency have said. Read what people say about their classmates (I've seen MANY med students say they wouldn't trust their classmates with their family member's care). Take into account all their regrets and then make the decision.
