vaginal pain!!!!

Every couple of days I get this vaginal soreness. Like how you feel when you have really hardcore sex. But I haven't had a lot of sex. Hurts when I sit down and walk. But today it's been excruciating pain. I can barely walk. I couldn't even put my pants on because I couldn't lift my leg up far enough. It feels like someone kicked me in the hooha as hard as they can. What is going on!?! Feel like I need to sit on an ice pack.
