One of my boobs is rock hard and painful

Sarah

What should I do? Is it a clogged duct? Just overly full? The trick is that I am trying to decrease my supply, so I’m not sure if I should pump more to relieve the pressure? Or is that just going to cause me to make more milk? My baby is formula fed and then I pump breastmilk bottles every other feed. I can’t breastfeed because we can’t get a latch, so I’m stuck to bottles but I want to significantly decrease my supply but im hurting. Help?
