I have a hostage situation where the villain is going to shoot one character in the shoulder (to cause severe damage to the joint), but another character pushes the first character out of the way, surprising the villain, and is hit instead. This takes place at close range and the villain is a good shot (it's a handgun, the bullets are full metal jacket). I want the character who is actually shot to require a few days of recovery/hospital time with maybe a couple of weeks of minor issues (lighter workload, not able to use one arm as much), or less. I read in another post a few years ago that someone suggested having the shot go through the arm and hit the bicep, which would only require an overnight hospital stay and some time in a sling? This might work, but I'd like to know more about what the treatment process would be like if possible.
Same situation, but later, the villain shoots another character from across the room in the upper body (chest/shoulder area or arm), and the bullet goes straight through without causing any serious damage. What would the treatment for this be like? Would they have to go to the hospital, and if so, how long would they stay? What lasting effects would there be?
