The 'big picture' of endometriosis. Pain and Endometriosis don’t always go together, but so often do - and it’s not just period pain. Dr Susan Evans is a gynaecologist, laparoscopic surgeon and author of 'Endometriosis and Pelvic Pain'. She illustrates how 'lesions' can be seen in the pelvis and removed in laparoscopic surgery. What if pain is severe, yet only a small amount of endometriosis is found? Are stabbing pains really due to lesions? Do lesions explain an irritable bowel, or food intolerance? How do headaches, fatigue, nausea, poor sleep, anxiety, low mood and dizziness fit in? What about an overactive bladder, painful vulval skin or painful intercourse?
