Nipple invagination must be corrected in time, and the commonly used methods are:

(1) Choosing the right bra size: Avoid and correct the bad practice of corset. Bras that are too small and too tight will oppress the chest and affect breathing. Because women mainly breathe in the chest, a tight bra is like tying a rope to the chest, which limits the breathing movement and avoids the further aggravation of nipple invagination.

(2) Pulling method: When finding the inverted nipple, gently pull the inverted nipple outward with your fingers every morning and evening. Gently massage the nipple with your thumb or forefinger, and pull it for 5- 10 minutes at a time.

(3) Extrusion method: use a smaller bra or cloth strip with the width of 10 cm to open a hole the size of a nipple, put on a bra or cloth strip to extrude the nipple outward, and persist for a period of time to make the invaginated nipple protrude. You can also buckle a walnut shell or porcelain wine glass on the nipple, put on a bra and press it for a while to make the nipple protrude.

(4) Negative pressure method: The thick end of the syringe or glass eye drop bottle can be buckled on the nipple, and the thin end is connected with a rubber tube and then connected with a large syringe. By forcibly pumping air, negative pressure is generated in the bottle, thus deeply compressing the tissues around the nipple and making the nipple protrude. After taking the bottle, combine pulling and massage.
