I separated my right shoulder (also a grade I/II) while skiing a few years back. Your doc has given you good information given my experience. Be careful over the next several weeks so that you don't injure your shoulder worse. When all is said and done, you'll have a a bit of a lump where your clavicle ends. My shoulder has recovered fully, but it has never felt quite the same as my left shoulder. It doesn't bother me; it's just a bit different now.

Good luck with the downtime - it hurts the worst.
