I Have Systemic Candidias (4 Different Types Of Yeast) And

I have systemic candidias (4 different types of yeast) and have had it since last March. I have Graves' disease as well and was just diagnosed with c. Diff. I have been on oral nystatin as well as dilflucion? My question is I have a appt with infectious disease at Vanderbilt on the 22 of Feb, what other treatments might be offered since these are not working?
