Hi, my name is Paulette, and I am 44 yrs old. When I discovered I had endometriosis, I was only 22. During that time, my daughter was 2 years old. I discovered this tingling pain on my left side/abdomen which was very uncomfortable. It felt like needles or pins, pinching my insides. When I finally got it looked into, my doctors diagnoised it as endometriosis. I had laser surgery and he put me on birth control pills afterwards to keep it from coming back and desolved. Thank God, it worked. I have not had that pain in over 20 years. I can suggest your daughter look into some form of birth control method once she get her problem looked into. I am now 44, and healthy.
Good luck.
