Nearly 3 years ago, I fell skiing and landed where my knee twisted in an abnormal way. It didn t hurt at first because I had taken something for my migraine before it happened. It barely swelled, but I went running the next day and it kept popping as I ran, plus, my knee feeling like it was collapsing under me every step I took. It still bothers me, but I have gotten used to the pain so didn t think it was serious. This past summer, someone I know said that based on the spot my knee has been bothering me, he thinks it s my MCL. After hearing this, I did research on MCL injuries and everything fits except for the fact my knee has been like this for 3 years
