Oh yes, she's only puked once (first time I gave expressed milk) and it was full of blood, totally panicked until I realised it was from the bleeding nipples 
Tried the medela nipple shields and though the pain was less, she fed for ages but didn't seem to be taking much in and when she came off the boob it still felt really engorged
The things that have helped me are:
On Saturday when she was 5 days old my poor nips were in such a state that I just expressed milk and gave her that for just over a day to try to give myself a chance to heal up a bit, did a mix of direct feeding and expressed milk feeding for a few days and have just been back on boob for the last couple of days.
Went to a breastfeeding drop in at the hospital and the midwife there showed me how hold her under my arm to feed, so even when the latch isn't great it's a different bit of the nipple taking the hit.
Lastly the bf supporter I saw on Wednesday called the health visitor and got her to get me a prescription for some gel wound dressings to help heal up even faster, only just got them tonight so finger crossed!
