Prostate infected with fungus/yeast

I had infection for around 2-3 years and I took all combination of antibiotics which never work. it came to an end when I took flucanazole. Everything was good after that and it went well for 6-7 months after that i got infected again i took antibiotics. It helps in controlling infection never cures. I started taking flucanazole again, I will feel better for 12-13 hours. Infection is still there.
