Tibial Bone contusion (bruise)

I had an ankle injury 4 months back. We assumed it was a ligament tear and used braces and bandage. But as the pain didn’t subside I have undergone an MRI and found that my tibial bone was bruised (contusion). Doctor advised me use miacalcic,celebrex and calcumum supplements. Any idea of any other treatment? how much more time it will take to cure this problem? what precautions I should take to avoid versioning of this problem.
