Suggest Treatment For Severe Itching In Labia Minora

I've had severe itching in the labia and sometimes near the vagina for about 2 weeks. It's been 2 weeks since that went away, but my discharge has become very watery and smells potato-ish and fishy. There would be white chunks from time to time, but it's just like water now. I've never had these kind of discharge before and my vagina has become very dry. Whenever I'm aroused, I'm dry and i can't get wet. it's so bad that when our genitals touch, it's sticky.
