What are your endometriosis symptoms like? I used to think excruciating back, leg, and abdomen pain was just a part of growing up. I remember running out of class in high school to vomit in the bathroom, feeling myself getting dizzier as I thought to myself “I guess girls just have it bad every month.” I didn’t realize that I wasn’t supposed to feel like I needed to take the week off from doing anything because the pain was so consistent.
