I'm running into an issue. I'm in the process of writing a story about a girl with a potentially debilitating disease, and her "adventures" in a fantasy world. However, I don't want her to be AS limited by the disease as people irl would be; or, I just want her to be LESS limited by it. More specifically: my protagonist has CIPA, a rare genetic disorder where individuals don't feel pain. Consequently, there are countless problems involved with these people; they often bite off their tongues, gouge out their eyes, (as babies), they feel no need to eat, they rarely live past the age of 3, etc. My protagonist is recruited into the faerie world (for more info, read Holly Black's books) for this specific trait. I'd like her to keep the aspect of painlessness, and perhaps some other negatives (feeling no hunger, inability to maintain body homeostasis <--up to a point!!). I DON'T want her to be constantly in and out of the doctor's office, like actual CIPA patients are. So, I'd like to write off her survival and relative good health partly due to magical interference (ahh, so cheap! x__x), but I don't know how far I can go and still keep the disease aspect believable. Any thoughts?
