Dear Sir, your MRI scan details your injury very well but a bit more technically, in common language you have torn your ligaments around your joint, but the good part is that they are partially torn, if there is swelling I would advise you to go and get a slab applied, because only a slab will give sufficient rest to your ankle that will help it heal its ligaments, if for any reason that is not possible, keep your limb on a pillow, and do not bear weight on it, give it rest for at least 3 weeks, followed by which you can start gradual exercises.
Next Steps
Apply a below knee slab, do not bear weight on the limb, keep elevated and analgesics when you have pain.
