Chest blockage refers to the blockage of milk ducts, which may cause a series of breast diseases. For example, during breastfeeding, a clogged breast may cause milk stagnation, breast lumps, redness, swelling, tingling and burning of the breasts affecting the child’s normal milk intake, and if not removed in time to discharge the residual milk, there is a high probability that it will lead to inflammation of the mammary glands or abscess, which will be even more difficult to treat. Breast enlargement may cause lumps in the breasts, breast pain, and abnormal nipple discharge, especially during the physiological cycle, when the symptoms are more obvious. In serious cases, it may cause other conditions such as breast damage, abscess, necrosis of part of the breast or breast cancer. Therefore, once a breast blockage occurs, it is best to go to the hospital in time to see a doctor, and actively carry out unclogging treatment to prevent the situation from becoming more serious.
