Well, I used to throw my back out occasionally. There are better carriers for helping with that...mei tais, mobi wrap, ergo. Basically, when I see my chiro, and keep up with my other issues through workouts, I can maintain health in my back. My lower back issues are a result of tight hamstrings...because I know that, I can work on my hamstrings to ease that burden, kwim? But, not everyone's backpain is the same. And it's debilitating when it hits. I feel your pain!
