I sprained my ankle when I was wrestling with my friend (as a joke, not serious fighting) on a surface that was steep. He pushed me sideways so that my ankle "rolled" inwards- I heard a few noises like cracking or something(like when you crack your fingers or your neck to ease tension).
In phisiotherapy I was given some exercises to do at home, but not necessarily just for the ankle erea (I was told it was for my whole leg-don't understand why though). The phisiotherapist says that I should also walk bare-footed on sand at the beach, because it trains the (I don't remember what they are called) on the side of the ankle, the part which I stretched or ripped. When I told her it hurts to do that, she said that if the pain is on a medium level- not completely unbereable- then I should do that.
So from what I understand: on one hand I need to rest the foot, so everything heals up, but on the other hand I need to strengthen it, even if that means I'm in pain(and pain is supposed to allert you you stop what you're doing).
Thanks for taking interest, and ask me more questions if you don't understand something.
So do you have any suggestions for me? Can you answer some of my questions?

Thanks again.
