I broke my ankle in Sep 2013. I had 2 screws and a device similar to a sling put in it. I began walking on it in Dec and had no pain until I started Cardiac rehab in Apr 2014. A recent xray says On the present examination metallic screws noted at the medial malleolus and the Union is incomplete at the medial malleolar fracture. Degenerative changes of right ankle noted with overlying soft tissue swelling . What can be done to help this ankle heal?
