Ok so I seem to be having a chronic problem with clogged milk ducts, especially in my right breast lately. I get rid of one and not two days later I've got another one. I nurse frequently, and gave up pumping entirely. I can usually get rid of the ducts within a day or two but they always come back. Is there any way I can help prevent getting them so often? They are very painful and make sleeping and nursing very uncomfortable.
