I have had 4 laps over the last 4 years and they have all shown endometriosis. My last lap showed no endo so consultant said my pain must be something else? I am very familour with the pain now and I am perplexed to say the least! I have started Zoladex injections 3 weeks ago and so far so good. Can you have endometriosis without it being seen on laparoscopy?
