i fractured my fibula about 2 and 1/2 months ago. doing sprints, i pivoted, twisted my ankle and then fell on top it. although it was borderline, i ultimately did not need surgery because the ankle was aligned - but now i have a non-union. doc says bone may never heal and that's ok - but the pain is unbearable. how long should i wait to try and heal on my own before trying to pursue surgery?
