Last year i was playing football (soccer) and i got injured in one of my matches, read desc please!!?

well basically i didn't connect to the ball properly as it was a 50/50 challenge, and basically my foot felt like it kind of popped, and there was a lump in the side of it. now a year later, the lump has gone down a bit, but after every football match it still hurts in the same place, what could be wrong?
