I Have Been Itching All Over For Over A Year

I have been itching all over for over a year now. After thorough reading I realize I have systemic Candida. It all started with years of taking Nexium 40mg everyday. Doctors never seem to tell me the right stuff. But the Internet has helped me tremendously. I am now on flucanozole. If that drug doesn't work,will I ever be able to cure my Candida?
