What causes nipple pain in women?
Generally, female nipple pain may be caused by menstrual cycle changes, improper underwear, pregnancy, nipple injury, nipple inflammation, and other reasons. After experiencing discomfort, patients are advised to seek timely medical attention at a formal hospital and receive treatment according to their specific condition. Detailed analysis is as follows:

1. Menstrual cycle changes: During menstruation, women experience changes in estrogen and progesterone levels, which may cause breast tissue edema and hyperplasia, leading to nipple pain. Sometimes it is accompanied by breast nodules or lumps. Usually, no special treatment is required, and symptoms gradually subside or disappear after menstruation.
2. Improper underwear: Underwear that is too tight or made of rough material may cause friction or pulling on the nipple, resulting in nipple swelling and pain. Severe cases may develop into nipple fissures. It is recommended to switch to loose, soft, and comfortable underwear to avoid friction and pulling on the nipples.
3. Pregnancy: Pregnancy causes significant hormonal changes in the body, especially increased estrogen and progesterone levels, which lead to breast tissue hyperplasia and increased blood flow, causing nipple sensitivity and pain. If the pain is severe, symptoms can be relieved by keeping the nipples dry and clean and avoiding excessive stimulation.
4. Nipple injury: Trauma such as bites or external impacts on the nipple can cause swelling and pain in the nipple area, sometimes accompanied by pus discharge. If the nipple is damaged, topical application of antibacterial ointments such as erythromycin ointment may be used to prevent infection. When necessary, medications such as ibuprofen sustained-release capsules, acetaminophen tablets, or Xiaojin Pills can be used under a doctor's guidance.
5. Nipple inflammation: Bacterial infection of the nipple causes nipple inflammation, presenting symptoms such as redness, swelling, pain, and itching of the nipple. Patients may use medications such as cefixime tablets, penicillin V potassium tablets, or amoxicillin capsules under a doctor's guidance to reduce the inflammatory response.
In daily life, it is recommended to maintain good living habits and avoid excessive fatigue to help prevent and alleviate nipple pain.
