Endometriosis is a common condition affecting around 5 or 10 in 100 women. It is a problem because it can cause pain, scarring and sometimes trouble getting pregnant.
Many women with pelvic pain have endometriosis, or have had endometriosis in the past. However the amount of endometriosis doesn’t fit well with the amount of pain. So, you can have severe endometriosis but no pain – or you can have mild endometriosis and lots of pain.
