#matthewc23 - That is a very unfortunate story and I am glad to hear that he managed to recover. I have had a swollen clavicle and my arm was in a sling for a few weeks. It was not that painful, but more annoying.
When I had a swollen clavicle it was a simple break in the bone and I only needed my arm in a sling for a short time. However, this also resulted in a bruise across my back which caused people to ask questions and also meant that I could not lean back in a chair with succumbing to some discomfort.
Despite this injury, I was back from it in a few weeks and I did not experience any complications. It was an incident that probably will not happen again and was an injury I view as minor in the course of my lifetime.
