Labia is hurting?

Jade
This is totally weird and it hasn't happened to me before, but my left labia minora is hurting really bad! I checked and there isn't any bump or red ness, but it almost feels like I rubbed sand paper on it or something, the skin is just very sensitive. It started hurting yesterday right before my period started, and whenever I wipe, it hurts like a bitch. I don't know why this is happening. I'm not using any new products or any soaps or anything on it. Anyone have any idea what this is? Also, about a week ago, I had a similar pain around my anus. I'm not sexually active either. Any ideas?
