ripping sensation in bottom of foot?

So, last year in July I sprained my left ankle pretty severely on a hike (I fell off a cliff! Oops!) What I found out after the fact is that my ankles are extremely mobile, ie: I can bend them a lot farther than I should be able to.

However, I still have a lot of numbness around the bone on the outside, and a lot of tenderness on the inside of my ankle, and often, when I try to take a step, it feels as if the bottom of my foot is about to rip out. Most every step is painful, which puts a damper on things like...walking.

I'm just a bit worried about this, because the sprain and swelling should have subsided MONTHS ago, according to my doctor it was only supposed to take a couple weeks for the pain to go away and the swelling may have taken a bit longer. Every once in awhile, my ankle gets pretty swollen. Not nearly as bad as when I first injured it but enough so that it's noticeable. The ripping sensation and the swelling don't always happen at the same time

I have it braced and wrapped (again...it's been almost 9 months of this crap) I've been keeping it elevated, and the ankle pain I was experiencing a couple days ago has gone away but the ripping sensation remains. Any thoughts? I'm not sure my doctor believes me anymore.
