Yes, I have it...was told for years that I didn't and was even given scans to prove it. However, after years of suffering, I was finally given a laparoscopy (which, according to my gynaecologist is the ONLY definitive way to diagnose) which confirmed I do have it. Some diathermy was done at that point, but for the last few months I've been having implants to put me through a temporary menopause which (in theory) will kill off the lining of the womb, thus killing off all the cells in places they shouldn't be...whether this works or not, I don't yet know. If you google endometriosis there are a lot of good sites which recommend dietary things and supplements etc, although to be honest I have tended to ignore the no caffeine and chocolate ones!
