I had 2 clogged milk ducts (just recently) with my newest baby. The first was early on, baby was maybe a month old. I let her nurse one evening while I watched tv for a couple of hours. I had tried everything and was afraid of infection. I nursed in different positions, I pumped, hot compress, ice packs, massaging... The only thing that worked was letting her nurse for as long as she wanted to. I was a human pacifier, basically! The second clogged duct, she wasn't interested in nursing for long periods of time. She got annoyed when I massaged while breastfeeding. It was frustrating. One morning I woke up with a fever, my lump was bright red, and that is a sign of infection. I had to get antibiotics, still could breastfeed, and it went away. If you ignore an infection it can cause major problems that require surgery, so if it doesn't get better, call your OB. It doesn't require an office visit, they should just call the antibiotic in to the pharmacy. Good luck!
