Sevre ankle injury

Im 14 years old.About 2 years ago I was playing basketball and took a big fall. I continued the rest of the game as my ankle pain shot through my whole leg. About a day later I went to a walk-in clinic where the x-rays showed nothing more than an enourmous amount of swelling. The doctor puzzled casted my ankle up for 2 weeks hoping to see improvments. 2 weeks were up and I was seeing the top orthopedic specialist in the area where he diagnosed it as “nothing more than a bad sprain”. Another year went by and the pain began to get worst and the color changing and swelling enourmous amounts. I was then taken 2 years after the injury back to see another specialist where he was also puzzeld with the whole situation and sent me for x-rays where once again nothing showed. I then went for a bone scan 2 months later and nothing showed. Doctor again puzzled sent me for an MRI where it showed, a break to the talus, a stress fracure in the foot, chips of bone floating around and a hematoma. Being the athlete I am I was devistated after being told 6 weeks in a cast. After the 6 weeks were up the cast came off and my foot was totally messed up. The heel of my foot was sticking out, and I had constant pain on the inner side of my ankle where I had never hurt before. So now I have bones sticking out of my foot and heel, and pain constantly, the more I walk on it the less it hurts until I sit down to relax where it swells up and turs colors in short periods of time. I am going back to see my doctor in a couple of weeks but after going 2 years with it broken im not too sure about his diagnosis, can anyone help me please!! If you have any ideas what so ever at what could be going on please help me, I play for the areas basketball team, the regional basketball team, and the provincial basketball team please I would like to make national team this year but it will be pretty hard if im in another cast!! I will take any advice you have I just want to get back on the courts, please and thank you!
