Help!!!

A few years ago i sprained my ankle and it never healed cause we never went to the hospital until a year later and said there’s nothing they can do so they told me just to ice and elevate. Every month it will start hurting but at the moment it’s at the worst it’s ever been. It feels like I need to crack it and it feels like I’m pinching a nerve. I don’t know what to do. When I originally hurt it I heard a crack and I fell down and could barely walk. We went in for x-rays a year later and they said it was a bad sprain. I heard the crack on the outside bone but it hurts on the inside. Ankle braces don’t help they just make it worse sometimes.
