Principal Causes of Breast Pain

The presence of some breast tenderness is normal, discomfort may be caused by hormonal changes due to:

Menopause (unless a woman is taking hormone replacement therapy).
Menstruation and premenstrual syndrome (PMS).
Pregnancy: the sensitivity tends to be more common during the first trimester and in pregnant women early.
Puberty in both boys and girls.
Shortly after having a baby, a woman's breasts may be swollen with milk, which can be very painful. If you also have an area of redness, call your doctor.

Breastfeeding itself may also cause breast pain.

The fibrocystic breast changes are a common cause of breast pain. Fibrocystic breast tissue contains lumps that tend to be more tender just before your menstrual period.

Certain medications may also cause breast pain, including:

Anadrol
chlorpromazine
Diuretics
Digitalis preparations
Methyldopa (Aldomet)
Spironolactone (Aldactone)
Shingles can lead to pain felt in the breast if the painful blistering rash appears on the skin over one of them.
