Re: Vasospasms or Thrush?
Flattened/striped nipples + nipples turning white + burning, throbbing pain = all very suggestive if vasospasm. Vasospasms are often mistaken for thrush, since both cause similar types of pain. If this is vasospasm, it's probably due to compression- that's what's giving you the flattened nipples- so the best thing to do is to try to get a better latch. This should happen naturally as the baby grows, but right now it may help to experiment with different positions, to go back to the LC and ask for help with something called the sandwich technique, and to make sure your baby is carefully checked for tongue tie. Treating vasospasms is generally easy- just apply heat the moment they strike. If heat improves the situation, then I think you can consider your vasospasm suspicion confirmed.
