Thrush and feeding...help please!!!!?

my daughter is six weeks old and has thush which makes nursing unbearably painful (to the point of crying and throwing up) its the second most painful thing ive ever experienced. (including a broken arm) obviously natural childbirth being the first. anyways...ive tried mycostatin, diflucan, colloidal silver, calendula gel, lansinoh, ice packs, heat packs, and nothing is giving me relief. anyone out there dealt with this and what was ur solution?
