Ah, welcome to the CCC - Cycling Collarbone Club. As LoFarkas said, it's the most common of non-head bike injuries, maybe even more common than head injuries.
I separated by collarbone last summer - not quite a break but I had a grade III separartion (the most severe kind) and mostly it ached for a few days (I still rode) but without surgery, it's permanently deformed. Since it's cosmetic and I kept up with physical rehab, I've opted not to do any cosmetic surgery.
Broken collarbones can heal is a few different ways. If not set right, the two ends can fuse on top of each creating a "bump" down the collarbone which I've seen on cyclists. Otherwise it'll set right. Keep the cycling light so it sets right (aka, don't re-break it) and keep up with either physical rehab or stretching and rotation exercises so you retain or work towards full range of motion.
