Fucking ouch dude. I've learned a little bit about that in one of my anatomy classes I'm taking, that shits no good. Basically, people with weak cartiledge around the bump on the outside of your ankle can have a tendon that runs under it slip up and over the knob, which makes your entire calf hurt like a bitch. That shit sucks.... I dont think theres much you can do, strength training to get the supporting muscles stronger after it heals?
