I've just been asked by an ob/gyn how to make a definitive diagnosis of ductal yeast in a breastfeeding woman 3 wks. post partum who is experiencing shooting pains in her breast. What a pleasure to find an ob so open to learning about treatment plans for yeast infection. I shared some information from Tom Hale's new book on Diflucan. Though I've searched Lactnet I haven't been able to locate any specific info on making a definitive diagnosis. Can anyone help? TIA.
