Hi, I have a 3 week old and have got mastitis for the second time in the same breast. I had it in the first week and had flucloxocillin antibiotics, it was a little painful then and uncomfortable when feeding. This time however it is much worse. It built up quicker, my boob is redder and much more painful, i have the same flucloxocillin antibiotics. I have had much worse symptoms with cold shivers and high temperatures. Has anyone else had symptoms like this or know of preventative measures. I am still breastfeeding and baby latches well.
