The only thins I have put in my ear to figth candida has been liquid magnesium: magnesium Oxide.
Earaches are due to a deficiency in magnesium and,as we know, candida depletes mag.
It found it to be utterly helpful and the earaches are gone.
Each time i would feel pain, I would put a drop of mag in my ears at bedtime. It worked marvel.
I had no equilibrium problems though, well actually very little and I was more suspicious of my thyroid than of my ears then because it always came along with die-off reactions.
The other treatment I would recommend is oil pulling [ visit the oil pulling forum for more details]. It is good for the entire sinus [ortho-rhino] area.
