I just finished my period. I've been using tampons since I was 16 and I'm 30 now. I've only had this problem once or twice before, but I'm in a lot of discomfort down there and itches so bad. Its not the labia or clitoris, it's right at the entrance to the vagina. I'm not swollen or red or anything, just itchy and uncomfortable. And it started after I started my period and of course, used tampons. I haven't changed brands or anything either.
