Re: Clogged milk duct for an exclusive pumper...
This was a huge problem for me when I was only pumping. The best advice I got was from our pediatrician.
Get a bowl of the hottest water you can tolerate. (Don't fill it too full, though, or it will overflow.) Lean over it and hang your breast in the bowl for a few minutes. Massage the clog and squeeze your nipple. If you don't see the clog at the nipple yet, do it again. You may need to reheat the water. The longest I had to do it was 30 minutes. This was the only thing that worked for me.
Hope you find relief soon!
