Could my ankle be sprained or what?

So, I severly sprained my ankle back in May and only stayed on the crutches for 4-5 of the 2 weeks I needed to. Back in July, it really hurt and the X-Rays came back showing that it was swollen still. Three weeks ago, I told my mom it hurt again and I wore an ankle brace for a few days. On Thursday, I hurt my wrist, but it doesn't hurt anymore. Now, my ankle is killing me so badly that I can barely walk! I want to use my crutches for a few days(like Tuesday-Friday) so that it will keep the pressure off of it. I don't want to use it on Monday because my friend is coming to observe my dance class, and I can't wait!!!

My ankle hurts really really really bad at times(especially when I walk, run, jog, or dance) and it's a sharp stabbing and shooting pain. Also, just a pain that I can't really describe. Pain: 8/10

What do you think it could be??? Also, how should I ask my mom if I can use the crutches for a few days? She'll think I'm jealous of my friend who's back on crutches, but I'm not!

Please help! Thanks!
