Hi I broke my fibula tube. My foot and toes are swollen and bruised and now I have a burning sensation at back of ankle is this normal?

Yes. You need to monitor the swelling because it can put pressure on the blood supply and the nerves.
Tough Break!! It could be. What is the extent of the treatment that you have received already? You might want to give your doctor a call to see if it is okay, based on what he has done already.
