For relief of thrush, bath the vaginal area with Bicarb soda with warm water (to balance PH levels) or even white vinegar with warm water to kill any external bacteria.
The vinegar will sting but it will relieve
the itchy feeling. Use warm hot packs to ease
the pain/itchiness. Only wear cotton underwear and loose clothing. Tight pants will irritate it even more. Stay away from foods with starch and yeast, and acidic foods/drinks.
