Since I'm still recovering from my double, I can say a few things. Stay more still than I did on the arm with the break. Having done both, I sorta had to decide which one to mess up this week. Having surgery on the right, meant keeping that side really really immobile for two weeks. Guess how many times I rebroke the left by the end of the two weeks. No matter how carefull, I just kept moving the broken ends around in there at least once a day, preventing them from staying stuck long enough to stay stuck. You will really be able to feel it when they start to knit, but you will need weeks more after they feel better before you can risk lifting any real weight with that arm. Avoid rebreaking it as much as possible. You will do it, I'm sure, maybe in your sleep if not while awake.
Fort up in the bed, and put lots of pillows under both arms, even the good one. This will help prevent rolling around and grinding those ends in your sleep. You are looking at at least six weeks of sleeping on your back, sleeping on the good side won't cut it. Stay on your back and pile up pillows to keep yourself that way for six weeks. I think at one point I was using 8 pillows when awake, and 6 when sleeping.
As soon as it starts to knit though, you will need to very carefully move around just enough to keep your range of motion. I did the karate kid routine while lying down, and at first, with the elbow still supported by the pillow. You know, wax on wax off, sand floor, and paint fence. If you do this, it will save you some physical therapy later. After healing, like six weeks, continue this stuff, but now with some weight in your hand. My PT was going to cost $25 a pop for the copay, so I did the karate kid enough to skip that expense.
For me at least, the weirdest thing was that I could still ride my bike allmost immediately after the accident, but I did have to stop after the surgery. After 10 grand worth of screws were put in, I couldn't risk wiggling them. But the way it works is like this.
What your collarbone actually does, is keep your shoulderblade, and arm attached to your body. You will find it feels like your arm is slowly sliding off your chest without it. Wierd forces start dragging on your shoulder muscles once there is no colarbone attachment to keep it all lined up like it should be. Enough bed rest, and as those muscles weaken, it may feel worse later on than it does now. So when you go out, you will want a sling for awhile, even after they take the packstrap thingy off you. For me, even with a sling, the worst thing was doctor office waiting room chairs without arms. Even if they had arms ,too short, and I was still suffering.
But what did feel good, was the frisk position, or anything similar, where I could lean on something with both hands, which took the weight off the arms, turning pulling on my arm into pushing on my arm. That would feel real good, and it was exactly the position I would be in on a bike. Since I own a trike, it was real easy for me to go for a very short ride everyday, except right after my surgery, without messing up the collarbones rebreaking them, or just moving them around before they set. I knew that too much bed rest was risking blood clots in the legs so I was pretty concerned about that with 6 weeks in bed coming. But I found riding the bike again suprisingly comfortable, and far better than trying to stroll around the neighborhood with both arms sliding down my body and hurting more every minuite. In my case slings were useless since I had to hang each one frome a broken collarbone. I immediately understood how Tyler Hamilton, and others in the TDF, do it. While riding, is likey the most comfortable they are all day. Just don't even think about falling off again untill really healed up. Just riding in a car scared the shit outta me for quite awhile with the seat belt strap across my shoulder.
Expect to feel not up to par for quite some time, far longer than the six weeks. Since I did both, I still have real problems lifting more than 50 pounds. As a construction guy this is really messed up for me, I expect to be able to tote 200 pounds if I need to. I still get unbeleivably tired unbeleivably fast if I use my arms too much. I don't know what you do for a living, but for a blue collar guy like me it's really tough. Good thing I'm the boss, but Its a working boss job, not a pure supervisor gig.
As for pain, I'm just a special case. I still have 99% of three kinds of painkillers they prescribed me. Mostly I just did normal doses of Tylenol, and then only when I had to go out to see a doctor, or go to work for an hour. Since I'm the boss, I had to keep showing up pretty much daily, but only for a few minuites. My pain tolerance is bizzarely high since back in 1976 I got burned pretty bad on both hands , arms, and feet. When they asked me to rate the pain of the collarbones in the ER, I said rate it how? They said, compare it to the worst thing you ever felt 1-10, so I gave it a 2. They said everybody rates it 10, and it kinda blew thier minds till I explained. When I got burned, that was real pain. I was working with contact cement, underdressed and barefoot, when the room blew up. Came flying outta there with my hair on fire and flaming glue on both hands and feet. Richard Pryor was right, you can realllly run fast when on fire.
Good luck healing. Fort up in the bed till it starts to knit together some, and get addicted to the ES. You can kill a lot of hours reading this whole site. Not long after I got pretty healed my laptop died from overuse. We won't mind a lot of posts with no capital letters.
