S.S.
Oh, I can definitely relate to you. When my daughter was 4 weeks old, we found out she had thrush - the doctor treated her but that white stuff on her tongue never really would go away, then one day while I was feeding her - yeeouch!!!! I felt like my nipples were on fire...I too tried gentian violet, but it did not work. I finally had my doctor prescribe me the Diflucan, and at the same time, a lactation nurse told me to put yeast infection cream (yes the kind for down there) on my nipples. She assured me it was safe for the baby...but I would dab it off before nursing and then put some more back on. Both of these methods seemed to work and after a week, I was feeling better. I know it's hard, I was taking Vicodin just to numb the pain of nursing. I got through it because I was so intent on breastfeeding. Just a couple of other tips in case you haven't already heard them...
-try to pump milk instead of letting the baby latch on if your baby will drink it in a bottle - much less painful
-wash nipples with warm water and let air dry after nursing or pumping and try to keep them uncovered
-if you are taking an oral antibiotic, eat yoghurt - it helps replenish the good bacteria in your body that gets killed with the antibiotic - this is very important
Good luck and if you choose to discontinue breastfeeding, don't let others make you feel bad - do what is right for you and your baby! But trust me, I've been there and I promise you will get through it!!!
Take care, S. S - mom of 7 year old and 2 1/2 year old
