Re: healing for a bite on breast?
Ouch! Poor mama. What you describe sounds like a very bad plugged duct, perhaps even the beginnings of mastitis. This can happen after trauma to the breast. This link covers What to do about it: http://www.kellymom.com/bf/concerns/mom/mastitis.html
Basically, you want to empty the affected breast as thoroughy and as often as possible, either by baby, hand, pump, or a combination of all three, and stay alert for symptoms of full-blown mastitis (aches, pains, flu-like feelings, red patches lrstreaks on the skin of the breast).
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
