Will an ankle lock (not any type of heel hook) break the ankle. I've heard it's just a pain submission, but I was also rolling one time and didn't tap. My ankle popped several times and my friend let go. It didn't hurt right away but the next morning I woke up and it was swollen for about two weeks. If he had kept cranking would it have broken or was that about the extent of the damage. Opinions? Examples?
