Welcome at Doctor Spring.
I have read your question with diligence.
Generally there are associated soft tissue & ligament injuries with fractures.The fibula bone is non weight bearing bone & it use to unite completely within 6-8 weeks.If there is still pain then i will advice you to consult to your doctor & have repeat x ray of your affected part.If needed you may also ask for MRI scan which will tell you about status of ligament & other soft tissue.
Hope this will help you.
Please feel free to ask followup questions / clarifications.
