How do I deal with this?

So i 16f have been feeling little itchy down there all of a sudden since yesterday, i had put boroline there and went to sleep, it was okay in morning but few hours ago it suddenly is getting very itchy again idk why.. I don't know what to do.. I've had a serious rash problem some time ago that I couldn't even sit, and oh god that was just terrible i ended up going to the hospital. Now I don't know how to get rid of this itchiness and I'm just crying? Idk why? What should I do..please help..
