Recently I went down in my soccer game and I was told by the ER that I strained my upper superior ligament, or something of the sort. It's been a week and two days, and today was my first day even remotely being able to walk..What should I do to increase my strength in my ankle and get back to playing as fast as possible?
Ligament strain in your ankle? You're now past a week so most of the swelling should have gone away. My advice is to go see a physiotherapist. They will help you out by:
The typical healing time for a sprain is 3 weeks - you're not even half way.
It's important to let it heal properly or it will either be too loose (and sprain again) or too tight and cause you flexibility and pain problems.
You've got a whole lifetime to enjoy your ankle. Getting back to your sport a week or two earlier pales in comparison with that.
