Mark, I wouldn't use your arm at all... my shoulder is now super freaky from being advised that it was simply bruised and not broken and me painfully trying to use it.
If you want to avoid that "winter set in" feeling and don't want to have a loose (manipulatable/sloping/tense) shoulder joint I'd just leave it be (at least for the 3 weeks or so), with it resting in as much of a "normal" position as is possible... just my personal experience.
