I am 29 years old, I have had endometriosis and PCOS for around 3 years now. 4 laparoscopic surgies, ovarian drilling, partial hysterectomy, and so on....recently my hair has been falling out, especially after showering. Hair is always coming out when I brush it or run my fingers through it. Also, I have been real tired all the time as well as having cramp like pain. I also felt somwthing by my right ovary that feels like a small hard pebble and hurts when i touch it. Does this mean my ovarian cysts have come back again? I just had surgery for ovarian drilling this past April. Should I be concerned about cancer?
