Iv had pain in my left pelvic area from before i started my periods and very rarely does that pain leave me and i'm 73 yrs of age now. doubled up in agony at any time of my cycle especially for a few days during. I had 4 miscarriages and a hysterectomy before reading my notes and finding out i had endo. I still suffer in agony at times and have been told its scar tissue.since iv been on a low carb diet and i eat as little processed food as possible i have to say i have suffered less. Probably once every 3/4 weeks i have a day with strong pelvic pain but i'm now able to live a much healthier active life.
