Try coconut oil, I have started putting it on before bed and in the morning and after each bm. Wash all linens daily, change underwear frequently, anytime ur itchy. I shower morning and night with tea tree oil soap. Its helped a lot. I also have severe itchy nose that feels the same as my nipples did when me and baby had thrush. May be candida. Coconut oil helps a lo tho. Instantly stops itching for me.
