They told me that I'd never have full ROM again after I broke my elbow, but I proved them wrong. When my back problems finally made themselves fully known, they told me I'd be in a wheelchair for the rest of my life and, again, I proved them wrong (to a certain extent anyway). The doctors often don't recognize the power of their patients' determination and courage. Go for it! Just know your limits and don't push too hard too fast or they'll be pulling a knife on you again.
