I had this happen to me when I was pregnant with my oldest son (he's seven now). But I had one the size of a golf ball on my vagina lip (Sorry for the visual). But I went to the hospital for them to lance it. And they gave me what I think was some sort of antibiotics. And after that they didnt come back. I also had to change my diet because I found out that the boils were due to toxins and excess waste in my body (I ate alot of junk during this time).
Sorry to hear about your whole insurance situation. But that's crazy that you can get care even if your pregnant. If I were you I would go to her supervisor or manager to have this situation addressed.
