Oh no! I began having a vaginal yeast infection from using Zithromax and yesterday decided to skip my Zithromax dose and began using Monistat. Then, just this morning, when Alex was feeding I felt a really hot, burning sensation from my nipple all the way up to my armpit. Based on what I had read while attempting to see what was okay to treat my vaginal yeast infection with while nursing, I'm almost positive I have thrush. What should I do? I was going to quit nursing soon anyway, so should I just stop? What's the best treatment for thrush? Please, please I really need help.
