LO is 7 weeks old and breastfeeding has never been free of pain for me. It had gotten better for awhile and I thought it was all going well but in the past week and a half my "nipple soreness" has gotten a lot worse, especially on my left side. On the left side after every nursing session for the past week I've had throbbing pain that goes deep into the breast and sometimes feels like it goes all the way through to my back? It seems worst after E's night feeding and has gotten to the point where it's hard to fall back asleep through the pain. I was so scared to nurse on that side that I nursed exclusively on the right and pumped the painful side.

I've seen a lactation consultant multiple times and she's never seen a problem with his latch- he always nurses perfectly there.

I'm not sure what to do.... Any advice?
