Ankle and and joint pain. To left leg?

I was playing football and I heard a small sound when I tried to move my right leg from the shin area of my right leg. After that I couldn't walk and my leg got swollen. After a couple of days swelling reduced, I tried to kick the ball once and then realized that there was something wrong from my ankle up to the shin. After 3 weeks now I am able to walk but can't play, when I exert pressure there is pain in the right side of the ankle part of the right leg near the round bone. That region is still swelled up compared with my left leg. I can't sit in the position one sits in an Indian closet and also can't bend my right leg and place it on the wall, both cases it starts paining not only ankle area but the shin area as well. The part in yellow is where it's paining and which is swelled up compared to left leg
