Ultimately you need to address the cause to prevent it recurring. What you did treats it and that's the ideal way to treat it, but you need to address the cause Could be an oversupply. I found when I stopped pumping and therefore reduced my supply I stopped getting blocked ducts but that's me. I'm not suggesting it's the same for you. Could be your sleeping position or your bra.... I'd talk to a lactation consultant
Have you tried taking sunflower lecithin? That helps me when I get uncomfortable.
