Deep breast pain w/o clog

Tina
I have had a hard time with clogged ducts in my left breast. I finally decided to try to wean my DD at 6 weeks. That side isn't producing much milk anymore and she doesn't like to feed on it much. Today it was soft all day so I didn't pump much and now all of the sudden I have this awful searing pain deep inside. No clogged ducts that I can find. Any ideas? It's really painful.
