I have an Injured ankle, any ideas?

I was playing soccer and ended up kicking a guy in the shin guard with my inner ankle. It swelled up right away but I could walk off the field with a limp. I stretched a bit but when I left I had trouble walking on uneven ground. I went to the doctor the next day and he said it was a contusion and should be fine in the next week or so. The past 2 weeks it has improved a lot but ached when I stand still and swelled a lot when I don't have it raised. I has been painfull to press on the bruise and the ankle has been stiff. Today (2 weeks after the injury) the swelling is down quite a bit but still a bit swollen, I can not make a sharp right turn(it is the right ankle) I can put all my weight on th leg (could from the start) I can hit the ankle bone without any pain but if I rub around the bone it is painfull especially the point of impact. Also there is a bruise that is painfull to rub on my inner leg above the ankle. I can not run but can walk almost normal but with a small limp. Also my ankle is still stiff. I can move it in any direction with out pain except inward where it hurts if I go to far. Does anyone know if it may be more than a contusion or how long a contusion may take to heal on the ankle?
