Well the 10 years part I actually believe, I've had horrible periods since my teens = light headed, bloated tummy, staying home from school, hard to stand up, etc.. and it's only now mid twenties after seeing a new doctor and explaining to her that I kept vomiting and staying in the shower spraying hot water on myself in complete agony for hours (3-5?), and that I was having a bloated stomach even outside of my period, not being able to clean myself, that she then thought I had endo and reccomended several tests including an endo specialist to verify it. And to think my gynaecologist didn't catch it, all jewish doctors are useless.
