[|Human|] my daughter has for years complained of a knot on her left lower abdomen. She is very uncomfortable at all times. Tests were done and all negative. MRI, cat scan , esophagoscopy , ultrasound, colonoscopy. What treatment do you recommend next. Would you recommend an exploratory surgery?
[|AI|]  Hi. The reason of a knot on lower abdomen with all the investigations can be a hernia only, or an intermittent spam of the local muscles being felt and painful sometimes and not at other times. More than the investigations Clinical/ Physical Examination is the most important. So consult a General Surgeon who is well-trained to find the rare cause of such symptoms which are not picked by any investigations. Colorectal Cancer could have been detected on all the investigations like CT scan and MRI already done. Colonoscopy to rule out such problems is highly recommended. MRI-Magnetic Resonance Imaging helps in the stationary organs and not in the moving organs like intestines.
