Thrush is more pain in the nipple itself. Sounds like a blocked duct.
Try warm washer before/while feeding, then cool after. Don't forget the trusty cabbage leaves
Just offer as often as possible. You could try pointing her chin in that direction. I heard it once & when I was all blocked up it seemed to help.
Good luck. Hope it gets better really soon x
I had a similar problem a month or so ago - I basically ignored it and it went away (probably not advisable - it only hurt when i touched or brushed it accidentally, as if there was a little sore there (which there wasn't, at least not that i could see!). The only thing i could think of was that DD's teeth might have grazed it during a nighttime feed. Do you think that might be what's happened to you? Hope it goes away soon, whatever it is. Do you have a good GP you can go and see?
