Hello moms. Happy New Year! ??? I have such a situation - my breasts are very swollen, I started having trouble walking from pain, it's like I have mastitis on both breasts. It burns and aches. This all started in the morning, it hasn't gone away yet. What can I do so that it doesn't get worse? Milk is still coming (the baby refused to breastfeed and I got pregnant right away) I think I should express, but I'm afraid of making it worse. Have you ever experienced this? How should I proceed? Right now I'm lying down to sleep and I can't fall asleep because of the pain.
