Lisfranc Fracture

I had a Lisfranc Fracture last year.
I referee football as well do some running, and am currently beginning to feel quite a bit of discomfort along the line where my foot was fractured.
I am afraid I may be reaggravating the injury or causing a stress fracture. What type of brace or support would you recommend to help alleviate the discomfort and protect it from further damage?
