I have a sore upper palate. I have had it for about a week. I went into urgent care on sunday of this week, and was put on flagyl for BV, doxycycline for a UTI, and Dulfican for a yeast infection. I also think I have a cracked tooth. This is all such a bother. I don't know if I should wait this out, go to an endodontist, see my regualr doc or go to my dentist.
