I've been bf-ing my 9week old and have had problems with my right breast all along. It doesn't produce as much as my left, I keep getting blocked ducts and painful lumps that take days to go away. I can tolerate that but every couple of weeks I get this horrible pain in my right nipple only.
It lasts for days and is so painful I break out in sweat when I feed him on it. I don't get why it's only the right one. I've had his latch checked and it's fine. It's so bad today that I'm expressing the right one instead of having him feed on it. He feeds really often so having only one 'working' boob is a real pain!
What could the problem be?
