Imagine that you are exercising together at a gym. your friend suddenly gets sprained, and it is clear that he or she has suffered ankle sprain. luckily you know exactly what has happened. explain how your friend is suffering from injury, and you need to know that you need to know what to do. a more long answer

you can tell if they are limping or walking strange and or have a swelled up ankle they probably sprained it if you are unsure you can always ask an adult or professional for help.

you can definitely tell if they have a sprained ankle if they're, limping, kinda grunting, it swells up, or if they are sitting down holding their ankle

Explanation: if they sprained their ankle, it's probably cos, they put too much pressure on it, or they didn't pace themselves so they kinda bent it

this could be helped with some ice, or just a little rest but it's nothing too severe
