Fungus are very tenacious and have many ways to survive in the body. If topical application doesn't have an effect, it may may be a systemic problem. I would recommend the LifeForce Plan for that.
I have worked on people with a cold laser and have seen very good results that way. It can take a while, but over a few months, it may help the problem. Fungus have the ability to interfere with cell signaling and a cold laser can retsore proper cell signaling.
