What causes nipple pain at four months of pregnancy?

Nipple pain during the fourth month of pregnancy may be a normal physiological phenomenon, or it could result from pathological conditions such as nipple damage or mammary gland hyperplasia. Attention should be paid to breast hygiene, and timely medical evaluation and treatment are necessary to identify the underlying cause.

1. Physiological Causes

After conception, increased hormone levels in women stimulate the proliferation and development of mammary ducts, making the nipples more sensitive and potentially causing nipple pain. This condition usually does not require special treatment.

2. Pathological Conditions

1) Localized Damage

Different degrees of breast enlargement commonly occur during pregnancy. Wearing tight bras may lead to prolonged friction and irritation, resulting in nipple damage and associated pain. Under medical guidance, topical application of anti-inflammatory ointments such as erythromycin or chlortetracycline ointment may be used for treatment.

2) Mammary Gland Hyperplasia

In individuals with pre-existing mammary gland hyperplasia, hormonal changes during pregnancy can exacerbate the condition, leading to nipple pain. Because medication use is restricted during pregnancy, local heat compresses may help alleviate symptoms.

In addition, nipple pain could also stem from other conditions such as mastitis. It's important to avoid breast compression, frequently clean the area with warm water, and seek prompt medical evaluation to determine the cause and receive appropriate care.
