Was walking on a severe sprained ankle for 6 weeks. Had MRI which shows a fracture. Will the fact I was walking on it for so long complicate things?

Not enough info. you need to provide more specifics about what bone was fractured and how severe was the fracture. Generally, you likely did not permanent harm.
Usually not. It depends somewhat on the nature of the fracture itself. One if the more common things we will see is a non-displaced fracture of the distal fibula, and for those fractures it does not hurt to bear weight. Discuss with your doctor.
