I am sooo sorry you are dealing with this, I know it can be horrible and it sounds like you've got it bad! You can make it through this, though.
I had thrush, which is an overgrowth of yeast. If you have it on your nipples, your baby probably has it in her mouth as well and if you don't treat both of you, you will simply pass it back and forth. Talk to your baby's ped about what you can give daughter. Watch her bottom for signs of thrush in the diaper area (open raw spots and bumpy red rash).
Here is an LLL page with links to several articles about thrush, treating it, etc.
The important thing is to stay persistant. I dealt with thrush 3 seperate times and it drove me crazy. The first time I would be in tears nursing because it was so irritating and painful. Wash all your clothes, particularly bras, shirts, towels in hot water and add a cup of vinegar to every wash. Rinse your nipples in half vinegar/half water after feeds (once they are healed enough- vinegar might hurt with cracked nipples!), boil pacifiers, bottles, bottleparts, pump parts, toys baby puts in mouth for 20 minutes/day. These are all things other than the medication that you can do to help get the yeast out of your environment.
I'm not positive, but I think it might be best to keep nursing rather than pumping, even though there is gross stuff coming out of the cracks, but maybe someone else will chime in on that point.
Good luck and I hope you do continue to breastfeed through this. Once you've got it beat, it is soooooo much better!!!
