I had this on both of my children. On both I didn't make it past 3 weeks bfing.
Jelonet 'sandwich' was most effective, thick layer of lansinoh, square of jelonet, more lansinoh over the top then a breast pad. Remove and use a breast shield then reapply. Do this for 24 hrs, they heal amazingly!
I was told by everyone 'latch was fine'. Even after they healed, I'd cry before and during every feed and began to dread the time coming until the next feed. My daughter never seemed satisfied when feeding and would nuzzle, cry, pull on my nipples with her mouth and cry after every few sucks. After a night of literally 7 hours of her and me crying, agony, bleeding and her feeding (few sucks, screaming, few sucks screaming like she was starving) we both past out and woke up 40 mins later with her crying AGAIN for another feed. I just couldn't do it and gave her a bottle with a carton of oremade formula a neighbour had given a few days earlier. She fed happily, downed the whole lot, didn't cry once and ten slept, the most soundly and content that she had in the whole time I'd had her!
In hindsight, and reading up after exactly the same happening with my second (I was devastated I'd 'failed' a second time!) I KNOW the latch can't have been right! Like the poor little thing was sucking through a bent straw!
Anyway, my tale isn't to put you off! I'm CONVINCED if I had seen an expert it could have been sorted. I rang breast feeding consultants in my area but couldn't get to see one until two weeks later. By then I'd reached my limit (and so had the baby!!!)
I also want you to know, it's not the end of the world and you're not a failure if you decide to formula feed. I can honestly say, making the decision to admit defeat and bottle feed was (devastating at the time) but a relief. I finally was able to bond with my baby rather than resenting every time she wanted feeding and finally began to enjoy being a mum.
Not saying this to be slammed for not encouraging you, just my experience!
Fed is best. Happy mum=happy baby, look after you're own wellbeing whichever form feeding takes from here on in! Definitely contact support, but, if you reach your fill, go for a bottle and don't spend weeks filled with guilt (I did on my 1st!!!)
