Persistent nipple pain in the early weeks of breastfeeding that isn’t improved with a deep latch, or nipple pain that appears after several weeks or months of pain-free nursing, may be caused by thrush. Additional symptoms can include:

• Itchy or burning nipples that appear bright pink or red, shiny, flaky, and/or have a rash with tiny blisters
• Cracked nipples becoming deep without bleeding, often in a fold at the base of the nipple. Occasionally cracks are seen on the front surface of the nipple in a crevice
• Shooting pains in the breast during or after feedings
• Deep breast pain
• Nipples sting more after the feeding rather than during the feeding
