In this story, the hero and his half-brother get into a knock-down drag-out fight (one of those long-time-coming things). The fight begins when hero insults brother's mom, and brother--a usually prim and proper sort--punches him and knocks him into a heavy desk nearby. The impact with the desk causes the injury. Hero is so pissed (see "long time coming," above) that he doesn't really feel the pain and the fight continues for a few minutes till other members of the household break it up.
To be clear: it is not so severe a break that a lung or other organs are damaged.(It's 1853, and I need the guy to live through this, so it can't be that severe). I need him to be in pain and inconvenienced but not incapacitated or endangered.
Now, according to my sources, in a healthy adult the bone is essentially set within 3 months, though it wouldn't be completely healed for up to a year and a half. I'm wondering how much pain my hero would be in at, say, three weeks and six weeks after the injury and how active he could be. This affects the timing of later events in the story. I need him to be able to function somewhat normally--walking, eating, sleeping without undue distress--but to be at a disadvantage when he gets into a later fight, so I need an idea of how to time it all.
Thanks in advance for the help!
