Clogged milk ducts

I don’t know where else to post this.. but is anyone else having problems getting clogged milk ducts while breastfeeding? I have had one in my right breast for a month now. I had mastitis a month ago and went to doctor. They gave me antibiotics, but I believe was only for the rash I had. That cleared up, but my clogged milk duct will not go away. I have massaged it, hot shower, warmth on it. Nothing seems to help. Any ideas?
