Candida kidney infection - PLEASE HELP!

Hi,
Once again my candida has spreaded to my bladder (from gut). I didn't ve proper meds on time, so i started treatment pretty late. Then i didn't finish it, and it came back - it has happend to me at least twice in a row.

The problem is, im 90% sure that candida has spreader from my bladder to my kidneys (i ve kidneys inflamation).
I got pain in my back for almost month, and since week am sure the problem are kidneys :(((

I take lufenuron, just bought fluconazole, used nifuratel and i need apolactoferrin (can't get it fast)

WHAT ANTIFUNGALS OR OTHER DRUGS CAN I USE?
Please help!
