Hi, I have recieved my fit test results back, it is 400. Should I have my colonoscopy in the next 2 weeks? I'm panicking i have rectovaginal endometriosis, where by rectum and sigmoid are affected. Last time I had a colonoscopy I was in agony. Can they put me under? The sedation/gas air did nothing last time. I'm so worried, iv googled it's such a high result.
