Ankle achilles tendonitis problems?

So i sprained my ankle in the summer and it healed. A few moths ago the pain cam back and is really sharp when i dance on it. Its right in the back between my heal and achilles and pops painfully when i rotate it. The doc said it was tendonitis and the mri showed a torn ligament in the front of my ankle. HE gave me a brace and a 4 week PT prescription. Well now im two weeks into the PT and the lady said it shouldn't still be bothering me this much if it was just tendonitis because i haven't danced or done anything on it in over a month. So she wants to see my mri and wants me to go back to the doctor. Anyone have an idea of what could be wrong an what the treatment would be? what are the chances i need surgery? Thanks!
