Clogged duct

I'm 7 months pp. I haven't had a clogged duct since my milk first came in. I empty it frequently because my babe still won't take a bottle. I've been doing massages and heat while I pump. And obviously nursing when I can, but babe is definitely fussier on that side.. It just started this morning, but when can I expect it to get better?? It is so so sore and uncomfortable.
