You need to take up golf. The distraction of the game seems to be helping him.
I never has a twisted or broken ankle. What's the best recovery method, walking lightly on it or not using it at all?
It depends on how badly it's injured. It could just be a sprain or lightly bruised or there could be pulled or torn tendons. With my left ankle, the tendon partially detached and now sticks out if I bend my ankle a certain way.
I've had twisted/sprained ankles numerous times before, but that one took the cake.
In general whenever you have a sprain or injury like that you need to remember RICE (Rest Ice Compression Elevation). So, stay off of it, keep it chilled with ice, wrap it up tightly, and elevate it. This should reducing the chance of ruptured blood vessels pooling in the foot and causing severe swelling. It's important not to keep it completely immobile though. Flex the foot to stretch the Achilles tendon so it doesn't lock up.
If the pain lessens and it doesn't stay swollen for too long with the RICE method, you should be able to carefully walk on it within a day or two (again, depending on the severity). If it really starts to swell and bruise up or the pain does not subside, then it is best to go to the doctor.
One of the times I sprained my right ankle, I wasn't able to walk on it for a week-- I twisted it while rappelling off of the fire station with the boy scouts (my father was teaching them how to rappel). I didn't have my foot oriented properly as I was swinging down and I landed with my full weight plus the force of inertia on the side of my foot.
I think this time it helped that I didn't have to go to classes or do anything strenuous so I was able to rest.
I hope that answer made sense. LOL.
