If I have broken my clavicle (collarbone) and I can move my arm after a few days does that mean it has healed?

I broke my collar bone on Saturday, since then it has been extremely painful and hard to use it or raise it to a certain point. I spoke to my doctor and I got an X-ray and he said I had broken the clavicle, I have an appointment today for either surgery or another solution, I have been using a sling since Saturday and have been taking ibuprofen, my arm now feels a lot better, it feels as if it has healed, is there a possibility it could have already healed and the bones are back in place because of the sling or is it because I am taking pain relief?
