Question: how do you know if you have a yeast infection while breastfeeding?
Answer: Breast and nipple pain: Thrush can cause severe nipple pain. If you feel burning, itching, pins-and-needles, or a sharp, stabbing breast pain, or a pain deep in your breast, you might have thrush. 1﻿ Inflammation (swelling): If your nipples and areola are swollen and very red, it could indicate a yeast infection.
