I tore an ankle ligament in May 2013 and in July of 2014, I sprained the same ankle again. After these incidents, my ankle randomly hurts as I'm walking. If I stand up for too long, I feel dull pains. Do you think my ligament is permanently damaged?

Not permanently anyways, it's possible you'd have to resort to surgery or therapy. There were a couple years where I thought I had weak ankles, cause I kept reinjuring them.

But they got better during a long vacation from soccer, and I haven't problems since. Except for the occasional overworking out.

Rest is important. Rest can also help prevent problems.
