Re: Vasospasm, thrush or poor latch-on?
Welcome and congratulations on the new baby! Sounds like it's been an eventful- and challenging- month for you.
What you describe sounds like a lot of different issues all at once. The initial cracking and pain- that sounds like a latch problem, in part because things improved when you figured out how to get a better latch. The little bumps in the areola area- those could have been small plugged ducts. Again, the way they resolved is informative, since plugged ducts can be fixed with massage and draining of the breast.
The current problem is harder to figure out. On the one hand, nipple sensitivity, inflamed-looking nipples, and a burning sensation in between feedings... Well, that just screams thrush to me. Particularly as it kicked in after things started to get better, and because you had antibiotics.
But on the other hand, there are other potential causes for your pain. Lipstick nipples definitely indicate a latch problem, and vasospasm pain can be mistaken for thrush pain. In addition, vasospasms often occur when there's a latch problem.
I think you're right to treat this as thrush. But I think that you should also operate under the assumption that your latch still isn't quite right- so here are some resources that may help:
