What's wrong with my leg??

Let's see..a little over 2 years ago my leg was smashed in between a forklift and a pallet..almost 7k pounds and somehow it didn't break..or so they say :0. Anyways..it was smashed in my calf area down to just above my ankle..I went to the doctor immediately because ..i couldn't walk for one..and it huuuurrrt. I have this big dent in my leg to now..kinda cool. They did x-ray and said it wasn't broke or anything, just smashed bad, only tissue damage. I had this huge pocket of blood on the left side of my leg that started at the top and went all the way down to my ankle..was like jelly when i pushed on it, rippled like water :0. They said it would drain out by itself..and it should get better in a week or 2... It took almost 6 months for my leg to drain. My leg still swells when i am on it to much and also i can't put much pressure on it, like sitting on my knees, hurts in the bone area on the front. I had a MRI done as well and turned up nothing..What do u think is the problem?
