Hi all, was just wondering, when did your endo symptoms start? Most people who I have spoken to about this or read posts on here have had problems immediately upon stating their periods. I ask because I haven't always had problems, my periods were fine, light and pain free, until I was 19. things changed strangely when I got cold sores for the first time and a few months after I was getting chronic pelvic pain and extremely heavy periods. I know it sounds unlikely but it's the only link I can think of, and I've not yet heard of someone suddenly getting endo pains. Has anyone else suddenly started exhibiting endo symptoms after menstruating for years?
