LadyClaret I'm so sorry. I've been there. It's so bloody painful.
The BFN are absolutely brilliant at this. Mine was in the milk ducts so I had stabbing pains, after feeds, going right back under my arms and almost to my shoulderblades. Then there was the pain of latching on ....
I was just topping up the pain killers to get through it. And I've had four births with no pain killers!
In the end I was trying so many things I can't actually say for sure what sorted it out but I would advise you to tackle it on all fronts.
I'm actually 90% convinced the homeopath did it in the end. Do you know that some farmers use homeopathy when their cows get this? (That's according to my really great HV.)
So I took the thrush pills, I avoided sugar and yeast (so wine, bread etc ... even dried fruit - anyting with spores.) Your body craves these things which is somewhat cruel and bizarre. Don't listen to your body. It's the thrush talking. The fungus that wants feeding. Starve it!
Tea tree oil and garlice are great. Inside and out.
Lansinoh is the best - no the only good nipple cream and made of nice gentle stuff (lanolin) and you don't need to wash it off between feeds. It's great for cracked nipples which you often get with thrush.
Also put Tea tree oil in the washing machine, especially with bras.
Keep treating your baby too.
Good luck. It will pass. It is horrible though and you may have to force your doc to give the correct fluconazole dose (I did) because they don't recognise milk duct thrush. It's not in their study books.
Also it's expensive so they may be reluctant to prescribe.
