Do i need to go to a doctor?

ISo end of july I whacked my shins on this bar when i fell, the swelling immediately dropped to my ankle. I went to the doctor when it happened nothing was broken. "just dont run for a while" (im in cross country and track) so i dont run for like a month swelling doesnt go away. i go to the school trainer for treatment. gave up. and continued to run on it. it doesnt hurt at all. its just very swollen and has a little discoloring. It is now almost January and still looks the same. Can i just leave it, cuz i really dont care, or is it something that will get worse?
