My foot is cracking?

My foot makes a strange cracking sound?

• You know the movement of stepping on the gas? When your feet rotate about your ankle (the axis)? When I do that with my left leg it makes a strange cracking sound which sounds exactly like cracking knuckles. And I dunno if I imagined it or what but it seems like it's sprained (or maybe it's because I walk awkwardly to try not to trigger that sound) Oh and it doesn't hurt not one bit. Is it normal?

• Answer:

  The cracking noise you hear is your ankle joint moving. Like you said, it sounds like cracking your knuckles...that is because the same thing is happening in the ankle joints. There is fluid in most of the joints (knuckles, ankle..etc). When we move the joint is a specific way, the fluid squirts or "pops". That is what you would feel as the "popping" sensation. The sound you hear (cracking) is the noise that comes from the fluid leaving the joint. If you hurt your ankle, it would not make noise. It would just hurt.
