I am a 42 yr old female who hasnt been to the gynecologist this year and i have a place, which resembles a dark vein, located just inside my labia. It was painful to touch at first and was difficult for me to get a good look at but it calmed until I had a difficult bowel movement and if I strained, that area seemed to throb. Afterward, it continued to be painful with sharp tingles. I became scared, wondering if it could be an annurysm?
