Small grains of flesh on the breasts during pregnancy are a normal physiological phenomenon and should not be overly stressed. The increase in estrogen throughout pregnancy leads to hypertrophy of the sebaceous glands around the nipples, which protrude from the skin surface to form a nodular bulge, also known as a Montserrat nodule. The main function of Montserrat’s nodules is to secrete oil and other ingredients to nourish and lubricate the nipple and areola to prevent dryness and cracking of the nipple, but if Montserrat’s nodules are enlarged and painful, and the surrounding skin is red and swollen, there may be a combination of infection. You can apply topical erythromycin ointment or fotarine for local analgesia. Go to a regular hospital for breast surgery or dermatology in time for a clear diagnosis and active treatment. You should avoid spicy and stimulating food, mainly fiber-rich and vitamin-rich food, such as vegetables and fruits, and wear loose underwear to avoid squeezing your breasts and keep your nipples locally clean.
