Discovering bumps inside my virgina what could it be?

I am a worried girl that has discovered lumps inside my virgina that feels like your taste buds. It does cause pain down there but they aren't sore or painful, it's just pain and also it burns down there sometimes mostly when im sitting. sometimes it makes my outta thigh itch. I did have unprotected which was 2 years ago and haven't slept with a guy since then. I've just did abit of home work on the web with people that has simular problems only they mensioned they were virgins so im just curious, if someone knows what this is please comment. gladly I am getting this sorted out this week at the doctors with a smear test added to it.
