Hi, I Had Ankle Fracture And Pain Not In Control,

Hi,
i had ankle fracture and pain not in control, sumtimes i con't tolerate pain and keeps on swell if put pressure on it. later doctor says i have bone SPUR in ankle that causing pain. so he advice me has to do operation to remove it. That's helps reduce pain after trimming spur, what he says. Question is thus it grow back? thus it trouble in my future activities? Isit dangerous?
