I am a mother of four beautiful sons and have successfully nursed and weaned them without incident until now. I just finished weaning my youngest son and am now suffering with incredibly painful breast tenderness. As I have never experienced such a problem with this in the past, I am at a loss for the cause and how to relieve this. I am not engorged and do not have an infection as far as I can tell. I have tried wearing a more snug bra and cool compresses. I have just started taking a progestin only bcp, and have considered that as a potential cause. Friends and co-workers all immediately jump to the pregnancy conclusion, but I had my period only 14 days ago, so I don't feel that is a potential cause. Any help or suggestions will be appreciated.
