Quoting: Lord Straylost
this has happened once in a session in GH2, in which I had 'repeatedly broken my bones', and the only doctor I could find opened a shop instead of healing me and tending to my injuries.
I'm not sure about GH2, but in GH1 "Your bones have been repeatedly broken" is one of 5
permanent injuries you can receive when you "die" in personal scale combat. The doctor can't fix this problem, so if you go to him with this problem and no other injury, he has nothing to do.
The only way to remove one of these injuries is to install cyberware of a sort that replaces your ruined body components. In GH1 for the broken bones status, these would be: "Reinforced Skeleton", "Lightened Skeleton", and "Heavy Lifting Skeletal Frame".
Of course, Cyberware is expensive and inferior in some significant respects to an uninjured character.
This aspect of the game is basically there to make up for the fact that you have no risk of losing your mecha in personal scale.
