Calf injury sysmtoms? PLEASE HELP!?!

On thursday i was playing football (soccer) and i twisted my leg and it felt like my fibula or God knows what, came out of place for 2 or 3 seconds then my soleus started hurting when i touched it. i sat down for about a min then i quickly went back in the game i could walk and run and even shoot the ball. This is the second time this has happened but the last time it happened was worst then now, it hurt a lot more and it took about 3 to 4 weeks to get better. This time it is getting better quickly then before. just in about 1 and half day my leg feels better
