Overview

Breast pain often relates to the menstrual cycle, pregnancy, or an ill-fitting bra. Ongoing one-sided pain with a lump or skin change deserves evaluation. Over-the-counter medicine alone is not a substitute for assessment.

Possible causes

Pregnancy or breastfeeding
Ill-fitting bra
Inflammation or infection
Chest wall muscle strain

When to see a doctor

See a clinic if pain is severe, one-sided, or comes with a lump, fever, or skin changes.
