What I need to know is this: I have a character that crash-lands on a planet and ends up with shrapnel in either her back, her hips, or her side somewhere. It needs to be not immediately fatal, and she doesn't notice it right away until the adrenaline wears off. Also, four people meet her at the crash site, and they don't immediately notice it either. She only notices after several minutes when the adrenaline wears off, and she collapses to her knees. It also needs to be able to be removed by someone who isn't a professional without said removal killing her. Her species of human have some regeneration ability (the wound will heal without a scar in a day or so once the shrapnel is removed) but otherwise have normal human anatomy and reactions.
I Googled various things like anatomy, shrapnel, and non-fatal wounds, and got too much that wasn't what I was looking for.
Thanks in advance!
