Firstly, congratulations on your new baby girl
I can completely relate, I had the same problem. I had very little help in the hospital and what help I did have was incorrect. By the time I got home one breast was unusable as the nipple had cracked sooo badly it was bleeding and within 2 days the other was just as bad. I hand expressed (very slowly at first) every feed for 2 weeks and bottle fed until the cracks had healed and I was able to reattach her without excruciating pain. Sounds like you had an equally painful experience with number1.
Does the hospital have a lactation consultant on duty? I have learned that in some hospitals you really need to push to see them. Otherwise it might be worth giving the Australian Breastfeeding Association helpline a call to have a chat and find out if there is a local consultant who can help in the next day or so. I hope all goes well for you really soon.
