Ligament injury. Your opinions on this.

I had my ligament injury and took a MRI which was reported as Grade 1 sprain of the deep deltoid ligament,Marrow contusion in the lateral Mallelous,mild ankle effusion... (the report was taken in the month of August and my injury had occurred on May 30) I had strained initially due to healing process has taken time and am in 6th month since the injury .i m doing my physiotherapy as well also able to run with the crepe bandage and do exercises in the gym. I don't feel pain when I do exercises but still there is some discomfort always which is nagging me also I could still see a bit of swelling ... since there is a discomfort my walk changes a bit automatically which is hurting my knees.please let me know how long will it take to get cured completely .It would be great if some one can suggest your opinions on this .thanks in advance
