Lobular hyperplasia causing pain during ovulation is normal. The main symptoms of breast hyperplasia are cyclical swelling and pain of the breasts, often appearing or worsening before menstruation and lessening or disappearing after menstruation. Generally, mild cases do not receive much attention from patients, but severe cases can affect daily life and work. Some patients do not show obvious cyclical changes, and symptoms can include unilateral or bilateral breast pain or cyclical changes, sharp pain, which can extend to the shoulder, upper limbs, or thoracic back area. A minority of patients may experience nipple discharge, which can be yellow-green, brown, or serous in color. The condition can persist for a long time, but symptoms usually disappear or decrease after menopause.
