It is normal to have swelling on one side and no swelling on the other side during the weaning process. Because of the development and growth of both breasts, they are often not identical. 1. If the distension is obvious during the weaning process, you can use a breast pump to suck out a little bit of breast milk. You can also take oral medication to promote weaning, such as vitamin B6, 20 capsules/time, 1 time/time, for 3 days, which can basically wean you. 4. symptomatic treatment drugs, such as ibuprofen, etc. Do not drink too much soup to avoid more milk production.
