There are lots of threads in Breastfeeding Challenges, but here's what I did (I've only had it once). I lay down in bed with a heating pad on the infected area, massaged it as much as I could, and took a TON of vitamin C, on the theory that my body needed it to fight off the infection. Mine came on really fast (Sat morning sleep-in til 10:45 and I felt a little engorged then, and by 11:15 I called my doc to see if I could get in because I had mastitis to get a prescription for antibiotics just in case). I started taking the vitC ~11:15 and ended up taking ~60g in 4 hours (during those 4 hours I had fever/chills, pain in my breast and general achiness all over, and a temp going up and down depending on how long it had been since the vitC). I have sodium ascorbate vitC in the house, and I ramped up to taking ~6g every 15 mins. I had no idea anyone could take that much--I certainly never had before. But the fever/chills/body aches went away and I got better. The newest edition of the magazine has a story on mastitis (recurrent, sounds like yours) and that may be of help with prevention/treatment as well. Good luck.
