i'm so sorry you're dealing with this- it sounds awful! it sounds like you're doing all the right things if it's just a latching/biting problem... but the fact that it's gone on for so long makes me wonder if it is thrush. the red, thin, peeling skin really sounds like thrush to me. do you ever have shooting pains in your breasts? that's another hallmark thrush symptom, but i still think you could have it even if you aren't having pain. i would give your doctor a call back and explain that it hasn't gotten better on its own, and ask if you could try a course of oral antifungals to see if it improves. you might also want to talk to your pediatrician and get a prescription for an oral antifungal for LO in case you're passing it back and forth.
