i dont know how long it will last or what treatments are the best but please if you want to continue to BF get on top of it now.......it sound like you already are but from my past exp if left untreated it can be unbearable. I had it so severely i would cry at the thought of BF and make DD wait for her feeds.. after 2 weeks of agony i got seen to but mentally i'd had enough. I think if i'd been seen to earlier (naiively i was hoping it would go away.....we were using only the oral cream) i would have stuck to BF. I felt so much guilt at failing to BF my DD past 7 wks. This time around i have so much support and wont hesitate to try and resolve any issues i get. Goodluck and i hope it works out for you.
