Why do my breasts still feel swollen after my period ends?

Some women experience breast tenderness or swelling during the premenstrual phase, after their menstrual period ends. This is commonly caused by rising estrogen levels. However, a colleague mentioned that her breasts still feel swollen and uncomfortable even after her period has ended. So why do breasts remain swollen post-menstruation?

Why Do Breasts Remain Swollen After Menstruation?

Persistent breast fullness or swelling following menstruation may indicate underlying breast conditions such as mammary lobular hyperplasia. Lobular hyperplasia typically causes breast distension, with symptoms often worsening before menstruation and easing somewhat afterward. Yet in some cases, swelling persists even after the period ends. A consultation with a breast specialist is recommended for proper evaluation. If lobular hyperplasia is diagnosed, medications such as Ruzengning (a traditional Chinese medicine formulation) may be prescribed. Additionally, avoiding physical and mental fatigue is important.

Warm compresses—such as those applied using a hot water bottle or heating pad—are a traditional Chinese medicine approach to alleviate breast distension. While warm compresses provide only temporary symptomatic relief and are not curative, they can help ease discomfort. Wearing well-fitting, supportive bras is essential; overly tight undergarments should be avoided. During exercise, always wear a sports-specific bra—not an ordinary bra—as this is critically important. Breast ptosis (sagging) or deformation may also contribute to breast discomfort and swelling.

It is advisable to avoid spicy, stimulating, cold, or greasy foods, and to refrain from consuming chicken. Tight-fitting undergarments should also be avoided. Maintain regular, adequate sleep. If breast pain becomes severe, promptly consult a breast specialist to rule out any pathological causes. We hope this information proves helpful!
