I have a pain inside my vagina that just occurs out of no where like just walking and it feels like someone is stabbing me with a knife, it takes me to my knees. I can't even move my legs to walk it hurts so bad. Do you have any idea what it might be? It does not occur during sex, or any strenuous activity, I was just standing there the other day when it occurred. Can you please help me?:confused:
