I fractured my lateral malleolus 4 weeks ago and did not know it. Went in and Dr. had it xrayed and it was fractured. What I want to know with all the pain and swelling that I am still having what is the best treatment? I have been put in a boot and prescribed physical therapy but when I saw xray there was a gap between the healing of the bones. Will this result in a nonunion healed bone and will I have problems later? At this point shouldnt it have healed on its own by now? I only went to Dr. because of the swelling, throbbing pain and difficulty walking on the affected ankle without a limp or pain. I still cannot stand on the ankle by itself without pain or instability. Your thought would be appreciated!
