The real question is, have you ever had one in your mouth? Otherwise known as thrush?
Sometimes I get them after having a particular strong antibiotic. So it's not enough to have been sick, then you have the sinus infection which needs to be treated, then you get thrush. So, we are going on a month now of different whoas.
Since I have not gone to the Dr. yet for the thrush medicine, I am hoping I do not find myself sucking on a tube of Monistat in the middle of the night.
