E.F.
I had several clogged ducts in the beginning; they are very painful. Besides advice that the other moms have given you, I would recommend a hot shower. Turn it as hot as you can stand it, and while the water hits your breast, massage it (hard). Start from the outside and massage inward (towards the nipple). This was the only thing that worked for me. It is painful, but it relieved the clog. Someone also recommended to me putting a hot compress on before nursing, but I don't think that will help you since you are trying to wean. Good luck!
