I'm familiar with what you're talking about because one of my friends whose daughter is just younger than my 8yo had a very, very large one on her forehead that they eventually deemed a health risk of some sort and removed. (She was happy because before that they'd told her that her state insurance wouldn't pay to get it removed even though it was HUGE and right in the middle of the forehead, because it was considered cosmetic. Sure, it's cosmetic, but sometimes for our little girls a few costmetics are needed!!)
Anyway, I just know what you mean and am not familiar at all with the meds or anything. Keep asking questions and demanding answers - if you aren't comfortable with something then make them help you GET comfortable or make them change it until you ARE. They work for you.
Hugs!
