Your orthopedic surgeon may be wrong, but he's less likely to be wrong then we are.

Maybe he's being overcautious -- if you wait another five weeks you'll be frustrated, but if he gives you the go ahead now and you have another fracture, you might sue him. So, ask him (or your primary care person) to refer you for a second opinion, ideally someone who works with a lot of athletes, can look at your individual case, and maybe guide you to the best path to getting back to running.

I sympathize with your frustration, but after 12 weeks out you don't want to blow it by going back too soon.

Good luck,

Robin

(PS -- I was out 11 weeks with what I am pretty sure was a proximal fibular stress fracture, but since I never actually got a medical evaluation and opinion, I did what seemed right, and it worked out fine )

The point is not so much whether you can run pain-free now, but whether you will pay a price later for impatience. None of us, including your doctor, want to see you go through the withdrawal we all would feel in your situation, but the ability of bone to knit properly with minimal calcium deposits is of primary importance to future chronic pain, especially within joints. If you need any additional inspiration, read the popular "Hip Arthroscopy" posts for a reality check on surgery and chronic pain. Yes, you could grit your teeth and suck it up for the rest of your life, but it would be better to take a chance on your physician's advice, and simply go through the process of of conditioning yourself to run all over again, a few more months down the line. At least you already know what you are in for! I once took 6 months off of running, and came back to set PRs years later. You can too!

You've already been out three months, surely you can wait one more.  Not easy, I know, but better safe than sorry.
