Just been reading other threads to try and find similar experience, have also read Kellymom pages. Woke this morning with left boob blocked, feels sore and lumpy. My DD cannot feed from that side, so have been expressing, but only very tiny bit coming out. Have had blocked duct before, but this feels like the whole boob is blocked. Have tried hot shower, bath, massage, hot cloth. Nothing is working. I don't have any flu symptons. Don't know what to do to unblock it!
