PFC,
My 1st concern would be to ensure your health and safety 1st and foremost, you are no good to yourself or the military if you put off what needs to be medically done or to ignore what could become a permanent disability, allow the docs to do what they need to do, if they are able to repair or build upon what is there, do your rehab, PT/OT, see where you are physically, they will try and do everything they can before boarding you for two reasons. 1st they don't want you to have a claim against the government, and 2nd they don't want you to be worse off physically than before they started working on you, that adds more issues to the problems that already exist.
Go through the process and procedures and you may be better off than before, just give it a chance.
Good luck, take care and have safe happy holidays.
Second, get better.
Stress fracture is a pain, because the damage heals slower than a normal break.
Broken hip is worse, because it is nearly impossible to isolate long enough to heal properly.
Finally, because a stress fracture is an overuse, activity related injury, a sports medicine doctor is usually the only one with the right background to create a proper treatment and rehabilitation program for you. Sports medicine in the Army has gotten a lot better, but it is still a long way from where it needs to be.
You are going to Bragg, accept that you will show up on profile. Bring your medical file, see your BDE physician or primary provider immediately (don't wait til you break again). See if they can get you a referral to a specialist, they will probably send you to orthopedics first (bones), but see if you can get a referral to the sports medicine guys. They should be able to set you up on a training and nutrition program (follow the program religiously) that will set you up for success, whether you get to stay in or find yourself transitioning.
The different services usually have people that inspire you to run faster, or harder, what they generally don't do is teach you how to run better.
Better running form is the only thing that is going to fix you long term.
Chances are, the drill will figure out your problem after 2 runs and you'll be stuck on crutches in holdover for the next 8 weeks. Get yourself fixed...
