About this symptom

Breasts Feel Heavy or Full

Breast changes can begin very soon after conception. Increasing levels of hormones cause increased blood flow and changes to the breast tissue. As milk ducts and milk-producing cells develop your breasts may feel swollen, tender or very sensitive to touch. You may also feel tingling, throbbing, burning sensation or itchiness. Your breasts may also grow in size, feel heavy or change in shape. As your body adjusts to the new surge of hormones any pain or discomfort should subside.
