I think you hit the nail on the head. this does sound like an inflamed plug duct,
You are right by not ignoring your symptoms. All the treatments you are using sound like you are on the right track.
i would add trying to get some extra rest. If you can spend the day in bed with your baby and pamper yourselves that might help clear this duct sooner.
If you start to feel flu like symptoms, and spike a fever well you know that it's not just a plug but mastitis.
I know you said you want to avoid the antibiotics but antibiotics are the correct scientific treatment for mastitis.
mastitis that keeps coming back has an underlying cause..
Those are some of the theories i've heard at LLL meetings.
It is also possible that you have a plugged duct and a yeast infection. Or your daughter irritated your nipple because she has a cold and is teething.
I kept my baby's nasal aspirator near me and I used it to clear up her snot clogged nose. When she could breathe better she nursed better.
