not sure what's wrong I'm 19 and recently had a very painful knee injury while playing soccer. I made a sudden twist that felt like my knee stayed behind and my foot turned. The pain was terrible I took one steps then fell to the ground because my knee just couldn't support my weight. I tried to stand and walk, but my kept on giving away. There was no swelling, but when I touch the sides of my knee, especially the inner side it hurts. I'm not able to walk normal because my knee feels like it's going to give out. Should I get an MRI or just see if it heals by its self?
