Bone bruises can take up to 12 weeks to heal, so I would be patient. When you rolled your ankle, one of the
bones in your
foot banged against another, causing a bruise. Essentially this is bleeding and swelling within the bone, and is usually self limitting, it gets better on its own. Before we had MRI, we didn't see these on xray, and they went untreated. Immobilzation in a removable brace usually is helpful in the acute phase, but at this point, I can't sayhow helpful it would be.
