Swelling never totally went away. One day I stepped on uneven ground and rolled my ankle. I barely felt it (nothing there to strain). My ankle was very unstable.
Really was a crappy experience. I've rolled an ankle a few time, but when I ruptured my ligaments it was extremely painful. The pain was unbearable.
If that sounds like your experience, I would push your doc to order an MRI. I wasted 6 months waiting for it to heal. When it was all said and done, I lost almost a year if physical activity in the prime of my life. Raw deal
