YES! I tore a ligament in my ankle in May of 2011! I still limp from it! It's awful! It used to make me super depressed, because I thought "pfft..can't do anything!"
BUT then I realized I am a machine hiding inside of a woman's body! I listen to my body while not pushing it, and do what my physiotherapist said. I do low impact cardio, like elliptical, punching, and one-legged freak jumping jacks. If my community had a pool, I'd use that too!
Ultimately, it took me almost two years to realize this injury wasn't going anywhere. I hope yours is not as long lasting, but regardless, there are many things you can do to succeed! I truly believe the injury setbacks are far more mental, since we are already nervous about losing weight without any added obstacles.
Hope this helps and good luck!
