So sorry to hear of your diagnosis. It can be a long road and one that you only want to be on once!
In general, if there was a stress fracture to get, the compression side (medial) is 'better' relative to the tension side (lateral). Follow the weight bearing and impact instructions from your physician to the letter. This can be frustrating, but in my experience the people that don't heal, return to impact or load bearing activity too quickly. I have had a patient go from a femoral neck stress fracture to a pubic rami stress fracture needing a bone stimulator (I can hear y'all snickering!) just because she refused to lay off. It was months longer rehab simply because she wanted to push.
Based on your ST name I am assuming you are female. This next part is easy to dismiss, but I would highly recommend additional work-up to ensure there is no evidence of osteoporosis. Stress fractures in female athletes are often a symptoms of larger dietary or metabolic changes. I would encourage you to ensure you know exactly what caused this and not just chalk it up to 'running a lot'. How is your diet? Your cycle? Iron levels? Vit D levels? Calcium? If all of these are truly fine as you are weaning back into activity ensure you have a good rehab team (Ortho, PT, DC, etc) that will appropriately balance your strengthening and analyze your gait during running, jogging and walking.
Good luck. The time to take to heal it NOW will be well worth it. Do it right the first time - pushing now is likely only to delay healing.
