Hi, I am an 18 year old male from Mississippi.. recently, my ankle has suddenly locked Up on me. I can move it downwords, as well as side-to-side, with little to no discomfort... But I physically cannot move it upwards towards my shin, and if I try to force it upwards it feels like it is about to break. It feels like it needs to pop , like the way you pop your knuckles or your back.. Can you tell me whats wrong with me?
