How recently is "recently applied"? Like this cycle in general but over the summer, or in October? And how many is a few DO schools? I would guess (not an expert) that if you didn't apply by the end of the summer, your odds are not great for this year. But there's really nothing you can do about this cycle at this point, except for maybe write some update letters and try to let the admissions offices know how super interested you are in their school. In spite of what schools may say about application deadlines, it's too late. I agree you should work on your MCAT. I took it twice, and improved my score by 4 points the second time. If I were a younger student (like in my 20's) I would have gone for the 3rd try, but I knew I was a solid DO candidate and still possibly an MD candidate with my stats. From what I know, you're at a serious disadvantage with an overall MCAT score below 500 or any individual section score below 125. At 497 you must be hitting both those points. Keep your fingers crossed for this cycle, but start exam prepping to take the MCAT in May and make that application killer, and submitted as soon as it opens! The other place you can stand out is in your letters. Are you sure they're the best they can be? Do you have a letter from a DO? If you're aiming DO be sure you do. I know schools accept MD letters but I'm pretty sure DO schools prefer DO letters.
Also, for perspective: if this is what you really believe you're meant to do, then you should absolutely give it another go. Look at where your weaknesses are on the MCAT, maybe take another class or 2 in those topics and improve your subject knowledge and sGPA while getting to know new professors intentionally to get some better letters, or more letters (I think I submitted 5 letters with my application plus a DO letter for those schools that required one). It's not so much that you're wasting your time...it's that you may need to take more time to beef up your application.
Podiatry seems like a reasonable option if you want to be in medicine but don't think you can move your stats at all. There are direct entry Nurse practitioner programs if you want to be a primary care provider: they do not require the MCAT or a BSN/RN. In many places NPs can now practice under their own license, so it seems like a reasonable option.
