I have some swelling on the right side of my labia majora. It is not painful except when I touch it even then, not so much. I've felt around down there and I don't feel any bumps or blisters or scratches.There is some discomfort when I sit or lay in certain positions. I'm currently on my period so I don't know if that has anything to do with it but I've never had something like this happen because of my period before. Wearing pads does add to the discomfort but I can't use tampons for personal reasons. I'm not sexually active so I know it's not std related. There is no pain or discomfort while urinating.
