Hiya hope someone can give me advice on this. One of my breasts is really sore and now its just started going a pink colour where the pain is. My baby doesn't like feeding from that breast i have noticed over the past couple of days. From late december i noticed a yellow bit on my nipple but the pain went eventually so thought nothing of it, the yellow bit stayed and now the pain is back again. Has it been blocked this whole entire time? I hope its not infected i dont want to take antibiotics because it gives my DD a poorly tummy. Two times i have had to take antibiotics for another infection and both times it affected my baby, the first time i thought it cant be the medicine can it? But when it happened a second time i knew it was the medicine. Please tell me what you think.
