Hi,
Did you try playing rugby today? If so, how did it go?
Considering you were able to hop, run, sprint and cut at sharp angles only 6 days post-injury, I do not suspect there was a significant amount of damage to the ankle ligaments during the injury.
It will be important to manage any remaining swelling using the compression bandage, icing and mobility exercises (circles with foot, sitting wit foot up etc.).
From there, I would suggest some calf stretches / massage as these muscles tend to tighten significantly as a result of this type of injury and may be why you get pain at end of range. I would then progress to practice balancing on 1 leg (eyes open and eyes closed) to see how much that has been affected (ligaments have a big part to play in balance and co-ordination). If all is pain free then ease back into running and return sport in a week or so.
Hope this helps.
