If the breasts have been traumatized or have recently been stressed and strained at work, the breasts will feel painful when pressed due to the poor functioning of qi and blood in the body. If it belongs to a woman’s menstrual period, or puberty, the breasts will also grow and develop more rapidly under the influence of various hormone secretions in the body, but if the nutrition at this time is not supplied in time, it will cause abnormal development of the breasts, which will result in painful pressure on the breasts. If you don’t pay attention to the hygiene of the nipple area or prefer to wear tight clothes, bacteria will accumulate in the nipple area and invade the soft tissues around the breast through the ducts, pulling the nerves near the breast and causing painful pressure on the breast. In addition, if there is mastitis or breast hyperplasia, ductal papilloma, or breast cancer, the painful pressure on the breast will also occur due to abnormal cell proliferation.
