Breastfeeding pain

Alison

My daughter is 13 1/2 months and has breastfed with no issues thus far. As of yesterday, my nipples are on fire. Idk how better to describe the pain. When she initially latches it’s painful and then the pain eases up a little. When she’s not feeding they feel sore. I’ve tried lanolin and breast milk on them, theirs no visible sores or cracks, and they don’t seem red. Has anyone else experienced this? I’ve never breastfed this long so I’m not sure if changes like this are normal as they grow and get teeth.
