Last Friday I found out I have a yeast infection, like real bad. It’s my first ever one. I got 1 day monostat and it didn’t work at all. The next day I was physically sick to my stomach because it hurt so bad. I started the 7 day treatment on Saturday. It started feeling so much better. I was finally in the mood again last night so my boyfriend and I had anal sex. However, I am in so much pain now again today... and itchy and everything. Have I undone all of the healing that has happened so far???
