Suggest Treatment For Itching In Clitoris

I have had an extremely itchy clitoris lately. It comes and goes throughout the day. No discharge or odor. The itching is not painful, and if i itch down there it feels very pleasurable and I get aroused. This constant itching is starting to get very annoying. When i was pregnant during the last year i had this occasionally but never persisting for as long as it has. I am 22, married and had a child 5 months ago. What could this be? Should I be worried?
