Clogged milk duct?

Maggie

Do clogged ducts always hurt? I’ve noticed that I have started to get little milk blebs around my nipples on both sides but they aren’t painful at all. I don’t know if that is a clogged milk duct or not? I have massages in the shower with hot water and they tend to go down but they return after a little while. Does that sound like a clogged duct or no?
