Ouch times 10?!

Ouch times 10?

My ankle is swollen and bruised and hurts to bend it or move it around. It doesnt hurt that much but It still hurts, its also tender. I dont remember any injury but I may have hurt it somehow. I can walk on it but I can't figure out why it is swollen. See on my left ankle it is hollow like it is supposed to be, but on my right ankle the hurt one it is round and It hurts. It is also purple which is why I think it is bruised. I am also 14 years old. I can also feel the bone on both ankles but the ankle is round on the right ankle. The round part that is bruised is on the inside of the ankle not on the outside. What do you think is wrong and what should I do for it

I think I may have twisted it coming down the stairs

You might have sprained (overstretch) a ligament or two. You might want to go to the doc to see how bad it is. Sprains may take 4-6weeks to get better if you keep the stable (no flip-flops, no open heel shoes, no heels) and rested. Put some ice over it and go to the doc.
