Yes, and this will sound absolutely silly, but it works absoluted magically.

Get yourself a whole head of cabbage. Take a large leaf, as large as will fit inside your bra on the affected breast, and put it in the bra and put the bra on. Leave it in place all day long.

A friend in La Leche league told me about this. When you feel it coming on, put the cabbage leaf in place and you'll never get mastitis again. And if you do it now, you can toss the rest of the antibiotics. Seriously. They're not good for the baby. WHATEVER YOU DO, DON'T STOP NURSING.

The acid juices might not be a good solution here--they can pass through the milk and upset the baby, like some other foods. I couldn't eat a lot of broccoli or beans when I was nursing because they upset the kids. You'll find lots of valuable nursing advice in The Womanly Art of Breastfeeding. This is a book I give to friends who are expecting their first babies. It helps with lots of topics, not just nursing.

PM me if you want.
