MRI or X-Ray for large stress fracture callus remodeling?

When you get a metatarsal stress fracture from running, if you get a crack in the bone, it will eventually start to heal. If you keep exercising, walking, running, doing elliptical training, and you are aggravating the fracture at all, the bone callus will get larger.  Over time, the bone callus will remodel, and that lump will get thinner. The lump of bone will get smaller. But if you are having pain because you have a huge lump of bone in your foot, at some point you might want to take a look at it with medical imaging.   Should I get an MRI or an X-ray when I have a large bone callus after a stress fracture, and I want to assess the callus remodeling?  Well, great question and that is what we're talking about today on the Doc On The Run Podcast.
