Under normal circumstances, because the nipple contains multiple openings of the mammary ducts, and the nipple area is more pigmented, so it is normal to feel the nipple is very rough, if there is no itching discomfort, or obvious symptoms of flaking, it is considered to be normal. The nipple has the opening of mammary duct, there will be secretion discharge, so the secretion will accumulate in the nipple area to form localized scabs, most of which will disappear when washing the nipple or taking a bath, and some of the sebaceous glands of the nipple will have sebum secretion, which will be restored to normal after cleaning. If there are localized lesions or rashes on the nipple, accompanied by itching and discomfort, you need to consider eczema on the nipple area, which manifests itself as rough skin, which is not normal and needs to be treated with symptomatic medication. In addition, localized allergies can also lead to skin roughness, so after the symptoms of discomfort, try to go to the hospital, and usually do a good job of nipple hygiene.
