Trish:
Because you had a colonoscopy 5 years ago REALLY tells us NOTHING about what you are going through today. I don't know what physician told you this, but I find MANY physicians are misinformed when it comes to colorectal issues.
Five years is CERTAINLY enough time for polyps to develop. How old are you? If you are still menstruating, does the pain relate in any way to your cycle? If so, it may be endometriosis, which can be EXTREMELY PAINFUL, where endometrial tissue "sprays" retrograde and sticks to the outside of your uterus, ovaries, colon, etc. During menstruation each month, these "patches" and nodules that form, bleed and swell just as the lining of your uterus does as you have your period. Some women experience very heavy bleeding, others not. Some experience EXCRUTIATING pain, while others feel little. This is usually diagnosed through an exploratory laparoscopy... a surgical procedure where your OB/GYN takes you to the OR and inserts a small port and camera and visualizes your organs. There are different treatments available if this is the case.
If it is GI related, then you need another colonoscopy. A CT scan does NOT always show the inside of your intestine and whether any polyps are present. I personally would start by visiting a GI, have a colonoscopy and rule out a GI issue before having exploratory surgery with your OBGYN.
I hope all this makes sense. I wish you luck. Please keep us posted.
