Unilateral Breast Milk Production After Weaning

Sudden unilateral breast discharge?

Hello, Doctor.
I gave birth to my first baby last August and started breastfeeding immediately after delivery, but the process was not smooth, especially with severe milk stasis in my right breast, which developed a significant hard lump.
Eventually, a physical therapist helped to drain it over several sessions.
I decided to wean off breastfeeding after one month postpartum to prioritize addressing the breast lump.
Recently, I have felt a slight foreign sensation in my right breast, but there is no pain.
Visually, my right breast appears larger than the left, and the nipples are at different heights.
I have tried lying down and raising my hands to check for any lumps or protrusions, but during repeated self-examinations, I only felt breast tissue.
What confuses me is that even though I have weaned for quite some time, I recently tried to express milk manually and was able to squeeze out a small amount of milk along with a bit of white discharge.
The milk is white but has a slightly skin-toned color; it only comes out when I squeeze.
I am unsure if this situation is still within the normal range.
Thank you, Doctor, for taking the time to respond.

More Info

Understanding unilateral breast milk production after weaning can be a complex issue, especially for mothers who have experienced difficulties during breastfeeding. Based on your description, it seems that you are experiencing some residual milk production in your right breast, which is not uncommon after weaning, particularly if you had issues such as blocked ducts during your breastfeeding journey.

Firstly, it is important to understand that after weaning, it is normal for some women to continue to produce small amounts of breast milk for a period of time. This can happen for several reasons, including hormonal fluctuations, the presence of residual milk in the ducts, or even stimulation of the breast tissue through touch or pressure. In your case, since you mentioned that you had significant issues with blocked ducts, it is possible that your body is still adjusting to the changes after weaning.

The fact that you are experiencing a slight difference in size and shape between your breasts, along with the ability to express a small amount of milk, could indicate that your right breast is still somewhat active in terms of milk production. This is not necessarily a cause for concern, especially if you are not experiencing any pain or discomfort. However, it is essential to monitor the situation closely.

Here are a few points to consider regarding your condition:
1. Residual Milk Production: After weaning, it is common for some women to experience residual milk production, especially if they had a history of breastfeeding difficulties. This can last for weeks or even months. The presence of a small amount of milk when you manually express your breast is generally considered normal.

2. Breast Changes: The differences in size and shape between your breasts could be due to various factors, including previous breastfeeding experiences, hormonal changes, or even the way your body responds to breastfeeding. If the difference is not accompanied by pain, redness, or any other concerning symptoms, it is likely not a significant issue.

3. Self-Examination: It is good that you are performing self-examinations to check for lumps or abnormalities. Continue to do this regularly, but if you notice any new changes, such as lumps, persistent pain, or changes in the skin texture of your breast, it would be wise to consult a healthcare professional.

4. Consulting a Specialist: If you have ongoing concerns about the size difference, the sensation of an "object" in your breast, or the milk production, it may be beneficial to consult with a lactation consultant or a healthcare provider who specializes in breast health. They can provide a thorough examination and offer personalized advice based on your specific situation.

5. Hormonal Factors: Hormonal changes after pregnancy and during the weaning process can affect breast tissue and milk production. If you have any concerns about your menstrual cycle or hormonal balance, discussing these with your healthcare provider can provide additional insights.

In conclusion, while it is not unusual to experience some residual milk production and changes in breast appearance after weaning, it is essential to remain vigilant and consult with a healthcare professional if you have any concerns. Your health and peace of mind are paramount, and seeking guidance can help ensure that everything is progressing normally.
