Not : Not all fractures show up on a standard x-ray, especially if they're hairline fractures. If you're starting to see bruising, you might have a little fracture. It takes 14 days for bone callus to be visible on an x-ray (bone callus is this white, fuzzy looking stuff that surrounds fractures as one of the stages of fracture healing), so you might want to have your ankle re-x-rayed after 2 weeks to see if there is bone callus. If you still have problems, an MRI would not only be able to show an occult fracture, but would also tell if you tore one or more ligaments.

All : All significant ankle sprains bruise and turn different colors for several days. Any sprain that is that significant should be managed by a sports specialist. Early therapy can reduce swelling and bruising significantly and allow for quicker recovery. Until you see a specialist, ice and elevate the ankle above heart and head 4-5x/day until the swelling and bruising look better. You can continue gentle range of motion ankle exercises as well.

Many possibilities: R.I.C.E. Rest, ice, compression, elevation. Immobilization with a splint or brace may be of benefit in the initial phase of recovery. Oral anti-inflammatory medication may help with the pain and swelling. Once improved, mobilization and physical therapy can help restore strength and function. Healing times may vary.
