Hi all, I am posting a case as requested by director of Women's Hospital,Indianapolis Lactation Center: For Maryann Monaghan,RN,IBCLC: We have the mom to an 8 month old complaining of burning,deep breast pain only in one side after feeds.Baby did have a diaper rash but mom had no s/s thrush on breasts....yet mom was treated for 3 weeks with nystatin cream and baby was treated for thrush( p.o.?) Both mom and babe were on antibx. prior to the advent of symptoms . The 3 week regimen improved diaper rash but no change or improvement in mom's pain. Mother now has a milk blister on the painful side's nipple,increasing pain-it appears after feeds.There is no use of tight or underwire bra and no s/s plugged ducts.Due to the milk blister and burning pain on the one side,mom is pumping that side this week and continuing nursing on opposite side. Any questions or suggestions are welcome.Does thrush occur unilaterally?There is a question of compliance with regards to yeast avoidance measures being followed by patient.The patient has been seen by a breast-friendly breast specialist(Dr Schmidt).We appreciate any input you can offer.
