I broke mine in four pieces when a road striping crew dumped about a gallon of glass beads on a downhill turn a quarter mile from my house. Was amazed the doc said no treatment. I don't remember advice given about when to return to activity. I did it on a Thursday, skippered a racing sailboat on Saturday and Sunday. My hip was just as painful as my shoulder. I had two weeks before riding the cycling leg of a sprint tri. I resumed training on the road four days later, and rode the tri on a hilly and curvy course on schedule. No problems with the shoulder at all now.
