 (Nick Galifianakis for The Post) | Adapted from an online discussion. Hi, Carolyn: I broke my shoulder six weeks ago and yesterday started physiotherapy. I have to do several exercises, several times a day, or I'll permanently lose my shoulder mobility. The problem is that they are really painful, and I have a low pain threshold. I can't use the excuse of time, because at the moment I have plenty of it. How can I motivate myself to do my exercises? Previous experience indicates that just willing myself to do them isn't terribly successful. Thank you. — Unmotivated |
