Seems to me the obvious answer is to go to [MENTION=342923]OldTryGuy[/MENTION]'s doctor .... no matter what happened.
I did my left collarbone five years ago. I left it alone for six weeks, then decided I could do weight lifting....
Another recovery period, insufficient, and I re-broke it again. (Yes, I can learn. Sometimes I just don't want to.)
The third time I waited until it was fully healed and worked back into it slowly. If I had done that the first time I probably could have been over it in under two months.
I probably could have started back with mild exercise at four weeks if I had been careful .... but then I wouldn't have these weird lumps all along my collarbone.
Take it slow, be careful, Don't Ride on the road (or rollers) for a couple months ... the last thing you want to think is "I should have waited" right after you fell to the left and snapped it again (just an opinion, based in prior idiocy.)
I did serious damage to my left elbow after an A/C separation several decades ago. I didn't have enough strength in my right arm to hold myself up after several days of my daily commute, so I learned to lean on my left arm .... which hurt for several years afterwards. More errors you don't have to make, thanks to those brave pioneers who should have known better.
