Dear Barb,
I sympathize......breastfeeding can be a real trial to start . I had similar problems and found that nipple shields did the trick. I also contacted La Leche League who gave lots of sound advice . They were very helpful.
p288 of T.S IYER recommends Sulphur for when nipples are sore and cracked or Nux for painful excoriation (would this cover the cracks I wonder ?????)
Most of the time sore nipples is due to not laching-on properly . I gave myself 2 weeks to get the hang of it and I'm glad I did but I had to go through the pain threshold first .
Calendula cream is very soothing..........
All the best
Scary Mary
