I'm nearly 9 months into bf ds3 and since yesterday evening have had a really sore blocked duct on one side.
There is a red fuzzy line coming from the nipple, am feeding him as much as possible and have taken ibuprofen - also done the hot bath thing and will continue to massage etc.
I do feel shivery but any fever is pretty low, ie not above 38 so far.
I'm hoping to avoid antibiotics as most of them make me ill, I can't take any cephalosporins, fluclox etc. so invariably have to stop the course, it is pointless taking them in the first place.
But I have three kids to cope with and not sure if I'm being overoptimistic.
I have had a lot of blocked ducts in this boob - it seems prone to them but only one or two mild episodes since he was born (had mastitis the week before he was born - that was great!) 
Any advice welcome.
