Hi A.,
I had the same problem when I tried to stop breastfeeding. I talked to a lactation specialist who told me to express a very little amount of milk from my breasts - just enough to relieve the pain. I have a breastpump, so I did that once a day for 2 days and then I started to feel the pain and fullness go away. You may want to try that. Hope it helps. Also, some people have told me to "bind" my breasts but I've heard that is very bad for you so I chose to go the other route.
