Not a good idea on its own. I think it is a great idea with context however.
A strike to the head could cause internal bleeding that only a autodoc or a CBM could fix. The symptoms would provide such comments and you would have to haul ass to a medical facility to turn on a CBM that would help heal the critical damage enough to set you back on the path of recuperation.
A snake bite could cause blood clots when to many bites are taken. Losing the function of the afflicted area until healed. So arms/legs taken to many snake bites wonāt let you do stuff similar to the appendage breaking. But it doesnāt heal at all like a broken bone should. It would have to be something like a shot. There is one, just googled it. Here is a snippet:
āAn injection of recombinant tissue plasminogen activator (tPA), also called alteplase, is considered the gold standard treatment for ischemic stroke. An injection of tPA is usually given through a vein in the arm. This potent clot-busting drug ideally is given within three hours of the stroke taking place.ā Perhaps risking brain damage and loss of motor function if not taken within the allotted time.
