I hurt my ankle and it still hurts a month later?

Back in late February, I play basketball, I had a game, I had went the whole doing great no problems, but then, I jumped up for a rebound, someone had pushed me while in the air, so I came back down like I was gonna land on my both my feet, I ended landing on my left ankle, inward, and when I did so, I felt it crunch and I believe i also heard it :(, but the pain just brought me down to the floor I couldnt step on it... but after I got out of the locker room I was able to walk a little bit. I woke up the next morning, forgot about my ankle, and went to walk to my closet, I felt a burning feeling in my ankle, and it hurt to put any pressure on it, my sister said it was swollen really bad. I went to school spent the day on crunches cause i had a game the next day, I played I was able to walk, and the swelling had went down. But now a month later, sometimes my ankel still hurts to move it inward, or point my foot downwards if i do it in the right position, and I cant point my foot inwards cause it hurts and feels like somehting is tearing, but it feels tense, i never went to the doctor either? Help anyone plz I dont know what to do or why it still hurts, this is the first time i have hurt myself like this in this kind of way
