Suggest Remedy For Sore And Dry Labia

I haven't had sex in about a week because I just got over my period. While wearing tampons it was irritating my labia. And felt dry. Now I'm done with my period and my labia stil are sore and dry. What is wrong with me? Do I have something? Or is there a remedy instead of just going to the hospital? (last night I tried to sleep with no panties on to let it get air but it didn't help.)
